BurnRX Revita Slim Weight loss pills, Internet

We ordered from the TV from one company, calling into a call center. Afterwards we received 3 times the shipment from 3 different companies, thinking we were only dealing with one company we called and cancelled, however the other two kept sending bottles at about $81 each.  It wasn't until speaking to them today that i realized there were indeed 3 different companies charging my credit card. 

I would like to know how they got my number. They must have given it to the other two. Contacting my credit card they have it on hold pending an investagation.  Talking to the BurnRX rep.  he stated that he had no idea about the other companies and how they got our credit card, but upon looking at the return address they all 3 had the same return address.  Talk about  a scam.  I am 80 yrs old and pride my self on being savy but this was an out and out scam.
