Four Sigmatic Reviews
Four Sigmatic's coffee products receive mixed feedback, with shoppers appreciating the quality and variety of the selection. However, the company faces significant operational challenges that dominate negative reviews. Customers report serious issues with unwanted recurring charges, difficulty reaching human customer support, and unresponsive service channels. Multiple reviewers describe being automatically enrolled in monthly subscriptions after signing up for free samples, leading to unauthorized charges that required intervention through payment processors or financial institutions.
Customer service emerges as the most consistent complaint across reviews. Shoppers describe inaccessible support systems relying heavily on automation, with templated AI responses and email channels that go unanswered for extended periods. The absence of published phone numbers and the difficulty in canceling subscriptions or resolving billing disputes leave customers frustrated. Even loyal customers who enjoy the product quality have stated they are considering switching brands due to these service failures.
The coffee selection is nice and varied, but the customer service is absolutely awful. They need to hire more actual people instead of relying on automation. There are way better chatbots out there that could provide better support. The whole experience has been so bad that I'm thinking about just switching to another brand.
This deserves a rating lower than one if possible. The coffee itself was decent but I was shocked to discover I somehow ended up subscribed to a monthly shipment charging me forty-five dollars every month. I had to get Pay Pal to stop the recurring charges since calling the two phone numbers listed didn't work and emails went nowhere. After many attempts they finally refunded and cancelled the subscription. These are bad actors and I'd avoid them.
Signed up for a free sample with just shipping and somehow ended up enrolled in monthly shipments being charged to my card automatically. Managed to cancel it I think, but I'm still watching to make sure nothing else charges. Didn't even create an actual account with them and they still set up recurring charges on my payment method.
Registered for a complimentary sample with just shipping costs, but then they just kept mailing me stuff and charging my card without stopping.
I genuinely love Four Sigmatic's coffee and have spent a lot of money with them, but I've reached my breaking point. Their customer support is nearly impossible to access. No phone number is published, everything goes through text or email, and responses take a week if you get them at all. When you finally do connect with someone, they won't actually help solve your problem. Then there's the sketchy side of their business. To cancel a subscription you have to click through like five different confirmation screens, so you think you've cancelled but haven't actually. They never tell you before charging for a subscription shipment, they just send it. It's not technically illegal but it's absolutely shady, especially when combined with how hard it is to actually cancel. Most decent companies give you a heads up and that should be standard practice. The worst part is they keep charging you on subscriptions you believe you cancelled because of all those confirmation screens.
Zero way to reach an actual human and all email support comes back as templated AI responses. They charged me even after I cancelled my subscription. The promotions they send out constantly are cheaper than having an actual subscription. I referred someone and never got the credit I was promised. Haven't been able to get any response about any of this.
Tried to get clarification on ordering to my country. I even sent them a photo of their delivery list showing my location wasn't included, but they insisted it was available. That response was completely unhelpful and honestly just frustrated me more.
Their customer service is horrible. I've been waiting nearly two weeks, sent multiple messages, and haven't received a single response. They charged my subscription and sent me the wrong items. This is just a complete breakdown of basic customer service.
Four Sigmatic's customer service is absolutely terrible. Their phone system is just an automated robot with no real options and they ignore text messages and emails. Don't count on any support from these people. They're shady too, automatically renewing subscriptions and charging your card without any advance notice or confirmation. Their customer support is disgraceful. I don't care how great the products supposedly are, if you won't provide honest, basic customer service you shouldn't be in business. They deserve zero stars for how they operate.
Got the SHIELD coffee in the green packaging and I'm really impressed. As someone who normally drinks tea, this has totally won me over. The taste is fantastic and I find myself looking forward to my morning cup. Would definitely recommend to anyone looking to try something new.
This company is genuinely fantastic! I've been buying their coffee for years now and it's the only one that doesn't upset my stomach after dealing with digestive problems for so long. Finding Four Sigmatic was a real blessing. I'd really recommend them to anyone who struggles with GI issues. The functional mushrooms in the blend make it perfect for my health needs and it actually tastes good too. Honestly the best coffee option available.
Horrible experience from start to finish. Ordered a protein powder that showed one thing online but arrived missing the main mushroom ingredients I paid for. Complained and got nothing but silence for weeks. Eventually had to message them on another platform just to get a response. They offered to send a replacement at no charge, which I appreciated, but when I asked to confirm it would have the proper ingredients they ghosted me again. Got a shipping notification saying it was delayed, then six weeks later the exact same wrong product showed up. Gave up after that. They clearly treat international customers like second-class citizens compared to US customers.
The coffee is really great and it's become essential to my daily routine. Their customer service team is fantastic too. The only downside is that the pricing is pretty steep, which is why I'm dropping a star.
Only tried their Functional Creamer since I use it for keto coffee. The powder came clumpy and needed a lot of work to break down properly. It claims to be like bulletproof coffee but honestly just making it with actual MCT oil and butter works way better. On the positive side, it did help me stay in my fasting window. The taste is basically nonexistent and you can barely tell it's there unless you load up on it. At thirty bucks a canister, I'm almost done with mine already and probably won't reorder.
