After reading the reviews where customers expressed difficulty canceling their subscription I’ve decided not to order at all. If it’s this difficult for people to cancel subscription it’s tells me a lot about this company’s product.

Tried to cancel subscription last October (5 months ago) by email since no phone # and or cancel options are provided, they ignored it -- only discovered it when a recurring payment went over my available balance, verify all your communications with this outfit - their response was this is a recurring subscription, BUT it was not a "forever" subscription, they have refused to refund payments

Not only did I not feel any difference in using the product I have canceled this product three times and they keep charging me buyer beware. Dr Emilio Castro

I canceled since I received no positive changes but they still charged me! I told them about it and discovered they made two accounts under my email so they could keep charging me. I do not recommend.

Firstly - I didn’t feel any positive effects, but some GI discomfort When I tried to cancel my subscription and close my account, I found it simply impossible! They made it not user friendly to cancel the subscriptions! Had to send an email requesting cancellation. If that doesn’t work, will be contacting BBB

I love this supplement and had a great experience when I needed to reach out to their customer service. I will never not take fatty15!

Just finishing up 9 months using Fatty 15, and I had high hopes for this product. I haven’t felt any difference whatsoever. Nice packaging, great customer service, but not what I hoped for. 😞
