Hi, debts dont get written off but if you have made no payments and no contact with the creditor and they have made no contact with you for 6 years (since last payment or contact not from the date of the loan) they are banned from chasing you, but if you act on any letters or phone calls etc the debt can become active again and they can start to chase you. My advise is to ignore this letter take a note of the return address on the back of the envelope and if you get anymore letters like this write not at the address and post it back. If you need any more info I am happy to help.
