Revival Soy review: Scammers

I signed up for revival soy for 30 day trial. If I did not like it I could send it back(which I did)and not be charged. I got a confirmation number when I cancelled and they claim they never got the package I sent but I have called them at least 7 times and they claim they got NO calls from me.they put this bogus bill in the collectors hands to ruin my credit. beware revival soy.
