OMG Tech Help Charged my credit card but did no work! Delray Beach Florida

 I called the phone number after buying software online to speed up my computer. As I was talking the person at the other endof the phone informed me that my pc was filled with viruses and he knew a company that could fix it.He also told me that he would be nice enough to take my $250 for having this "other" company fix my computer. He convinced me to pay him the $250 but by the time we were done speaking he tells me that the charge was $625!!!Instead of 1 pc, he added my husband's computer and then added 3 years of service. He ran my card and then told me that my pc would be fixed shortly! You know the rest. The computer was never touched and the company had my money. I tried to call back and was put on hold for almost 45 minutes. Some nice person in customer service (at least she said that she was in customer service) picked up and asked me what I wanted. As soon as I started to explain, she hung up. I called my credit card company and reported the company but I am sure that they will just close the doors and open in some other place and steal money from other people.
