The most f***ed up company I have had to deal with. The customer service was absolutely terrible, they will help you with absolutely nothing.
I talked with 3 different reps and all of them were extremely rude. They will talk over top of you while you are talking or asking a question.
The free trial they offer is most definitely not free, they charge you shipping to get it to your house which isnt bad, but they give you 30 day supply so you either have to pay for return shipping as well or they charge you for the bottle. The business they run is a scam and they try to get every cent from you by automatically charging your credit card....STAY AWAY FROM OPTIMAL STACK!!!!!
Reason of review: Poor customer service.
Monetary Loss: $22.
Preferred solution: Let the company propose a solution.
