Rude Service prescribed debt

I was contacted about a month ago by this company by some woman who informed me that she was phoning from DMC (debt management company) or whatever they call themselves at get this..... 06h00 in the morning. Firstly, secondly she was very abrupt and rude towards myself then thirdly she was asking for money for an account that was 10 years old which was bizarre - I asked her for a statement and when I got my statement it came from a company called [URL Removed] (which seems to be a Finance company and my statement was dated from 2012 but the account was from 2004). about a week later a reasonably helpful woman named tertia phoned me and told me that I owe money on the account on the same account . She then goes on to get this... OFFER ME A LOAN TO PAY OFF THE DEBT at a 50 percent discount as long as I supp**** my bank details. Surely this is a ****. When I logged on to HELLOPETER I realised I am not the first person to have dealt with this situation...
