Four Sigmatic has rubbish costumer service. Their phone system doesn't work, it's automated machine and they don't reply to text or email. Forget any help from them. They are sneaky, just charge your credit card in auto-renewal subscriptions without sending you any notification or confirmation from customers. Their lack of customer support is disgraceful and despicable. I don't care how "good" your product is, if you can not provide honest and decent customer support you should close your doors. Zero star is too much for them, they earn ZERO star.

Four Sigmatic is dishonest and unethical in how they handle orders. Their auto-renewal system is deceptive, charging me and shipping products without my confirmation. When I tried to contact support—three emails, two text messages, and three calls—I received absolutely NO response. This company operates with zero integrity, ignoring customer concerns and refusing to address issues. Their lack of transparency and customer support is disgraceful. Avoid this company at all costs!

The customer service is terrible. Also, they are now charging huge amounts for taxes to receive shipments, so I had to leave them after being ordering for over a year.

They are dishonest about the content and have "curated" (fake) reviews on the website. I ordered a creamer and noticed it didn't say how much L-theanine or lion's mane mushroom was a actually in the pack. I asked their customer service and got the reply was first inaccurate (they thought L-theanine was a mushroom extract) and then said they wouldn't disclose the information because it would "threaten the integrity of the brand" (their words). And that saying how much L-theanine (a very common green tea extract) would "compromise our competitive edge over our competitors". The only reason I see for keeping this secret is that they have an offensively small amount of it in the pack. And the cans of mushroom blend are more than 70% air to make it look like you´re getting more. After browsing the reviews on the website I could only find 5 star reviews after pages and pages and they look bot-generated. I looked into "yotpo." - the provider they use for "curating" the reviews and its a dishonest service. And on four sigmatic's website they have the guts to claim that they are "transparent".

Awful , awful, awful . Sent me the wrong protein as listed online missing all the main mushrooms, complained and ignored me for weeks and weeks no response in the end I had to chase via their instagram chat , then offered to resend me a new one free I replied thanks however please can I ensure it has main mushrooms ingredients ignored me again and again , received an email of dispatched with delay , then randomly 6 weeks later the same incorrect powder turned up yet again, gave up with them clearly international do not get the same service or products as the USA

Extremely sneaky company. I intended to only order the lions mane coffee but they sneakily included a 16 euro coffee creamer in the order. I did not intend to buy a creamer at all but they have a sneaky tactic employed. Watch out, its like being on the ryanair website u need to watch u don't buy or sign up to something u don't want or need

Extremely dishonest and shady company! As another reviewer mentioned, they completely ignore email communication so you probably won't be able to get a hold of them ever. STAY FAR AWAY!

I am seriously unhappy with the service of that company. I've ordered coffee from them, because I wanted to try and decide if I like it and then to consider subscription or ordering again. I've received the coffee on time, I've tried it and didn't really like it that much to even consider ordering again. Bear in mind, that the coffee is quite costly. After 2 weeks, Four Sigmatic took again the same amount of money from my card without my permission and they've send me again coffee. I wrote an email asking how can they decide from my behalf if I want to order again and they said that I have a subscription, which I've never made. I was really careful when I made the purchase, as I know a lot of companies are working like that, (tricked you in subscription), I didn't even made an account and did only one time purchase. They replied that they will cancel my subscription and will refund my money, which they never did. So I had to call my bank and ask for cancellation so to be able to have my money back after more then a month. Now, even though I cancelled many time the advertising emails that I am receiving, they continue to send them and I can't stop them. My overall experience was bad and I would never order from that company again.
