EMZ Shopping extramoneyzone.com Unauthorized Credit Card Charge, False Advertising, Internet

I received a text messaging telling me to call a number about "Mystery Shoppers". I did, and the woman on the phone told me there would be a 2.95 charge to my account, but that would be it for the next month. All I would have to do would is go online, select a store, mystery shop, and receive my $50. This was on 2/16/12. Immediately there was a 2.95, a 3.95, and a 49.95. And today there was another 49.95. This is not what I had agreed to. I called and the woman did not speak English, I could not understand her. She kept telling me that it was my misunderstanding. This is absolutely a SCAM!!!!!
