It turns out that you get the free trial from buyrezv.com, which automatically signs you up for the "membership". Then after your first bottle, you start receiving new bottles of RezV and that is when they start charging your credit card. However if you look at the card they send with the bottles, the name of the company is NutriBlvd (however your credit card still has company as buyresv.com with a bogus phone number next to the charge). You need to call the number on the card that was sent in the mail: 888-273-0308 to cancel your membership. I received an email confirming that my BOGUS "membership" was cancelled.
DO NOT open the bottles. You can send them back and apparently they will send you a refund. They will give you an RMA number and claim that they will credit you credit file. I will be sending my two bottles back on Monday.
If you don't mind spending more than a $1000 a year for a questionable product, then go ahead and remain a "member" and get one bottle a month. Personally, I buy many supplements and $90 a bottle (~$3 /day!) is what this stuff costs...that is insane.
I refuse to have anything to do with this very unscrupulous and unethical company who plays games like this with people's money. I strongly suggest that everyone who has been taken by this company, please cancel your membership and get a full refund, if you have not opened the second bottle.
