Once I knew I had no relationship with them (though they claimed to be calling to confirm my order), I started saying "Please don't call me." over and over again, louder every time. The woman on the line stayed on and kept talking until I had said it at least 20 times. Most telemarketers give up after three or four times being asked. I never say anything other than those four words, and they figure out that they are wasting their time.
They cell garcinia and I did but but found I was allergic to something they put in it. When I tried to cancel future orders, They said "too bad you committed to two more shipments and you will get them and be charged". They are worse than scum..I had to cancel my debit card to keep then from charging me. When I bought it the girl said that I could cancel before the first bottle arrives. They lie cheat and steal. Don't do business with them. After the first bottle it's they charge 40 bucks. Google it. I found something similar but better for 12.
Call them and threaten them with a Federal Lawsuit and follow-up with a letter. Cite the law they will back off. Tell them you know where the manager lives and will sue him too and place a lien on their home. Low life's trying to make a buck.
Also contact Federal Trade Comission and file a complaint.
