Slightly different thing with a bank. My dad rang me a couple of weeks ago to tell me he had found an old bank book of mine from 1992, it hadn't been used since then either and there was less than £100 quid in so I thought that it might be worth having a look at seeing if I could get the money back. Hey ho, found Martin Lewis's website has a link to the banking website site that tracks down old accounts.
So I fills in all the details from the passbook and waited, got an email back saying that it might take 2weeks or more to locate account details.
Less than 12 hours pass and the Northern Rock can confirm they have never heard of me or had any accounts in that name.
Strange, I had a savings account (pass book in my hand), current account, credit card and a loan….oh yes and I worked for them for a year. Nice to know I made a good impression on them as a customer.
