OMG Tech Help Used scare tactics, threat of imminent danger to my computer if I didn't immediately give them my credit card # . Delray Beach Florida

This company used scare tatics, played on my fears, predicted doom if I didn't give them my creit card # immediately & let them "fix" the thousand of malware ussues currently taking over the hard drive & infecting every aspect of my computer. The man told me it was just a matter of time before it would destroy everything on my hard drive.  I have since tried to call them to ask (at my credit card company's advice) that they refund my card.  I have been on hold several times for almost an hour & have not been able to talk to a live human being.  Now I have to advise my credit card company to dispute this charge to try to get my money back, file a report with the Better Business Bureau & do anything else I can do to let people know about this scam
