hi again, I just read your last post.
Theres quite a few scams going round that rely on folks paying up without question. The companys just stall and stall the person and keep on sending out 'you owe us this....' letters and threatening court action.
If you are being asked for money from someone claiming to be a credit company or debt collection agency and know for a fact you dont owe the money take a look at the letter they have sent you. The letter should have a registration number on. If you go to the Financial Services Authority website
http://www.fsa.gov.uk/ theres a section somewhere where you can put in the registration number and it will tell you if this is a real company or not. If it isnt then phone the FSA on the number on the page and they will take down the details and track the company down.
I used to work in a finance company and every letter we sent out to customers that owed money had their name, customer number, account number(s) for the accounts money was owed on, the starting date and balance and the balance owed when the letter was sent out.
