US Fast Cash SCAM SCAM SCAM SCAM Internet, Internet

I received a phone call today from a gentlemen claiming that he represented US Fast Cash.  He spoke in a heavy foreign accent.  He claimed that I was being charged with theft and all these other charges for a loan that was taken out in March 2011 and supposed to be repaid by November 2011.  It was for the amount of $300.  He said his name was Ben Johnson.  When I asked what banking facility this transaction was sent to he said that it was given to me on a prepaid Walmart Gift card.  I told him that this was bogus and that I had never obtained this loan.  He then started getting rude with me and said that I was going to be charged $5000.00 if I didn't pay it off today.  I told him to quit calling my number or I would report them.  He then said that because I was getting mad it was because I know that I owe this bill and that I had better pay them.  I have never used this company before.  The only online loans that I have ever acquired is through Plain Green Loans and they are absolutely wonderful.  These people are complete scammers!!!
