I got the letter as well. Called them to find out how they got my information in the first place as I only remember applying for some hire purchase through them around 15 years ago or more but I wasn't living at the address that's on the letter at the time. They couldn't even find my account when they searched using my name, phone number or license. They also couldn't tell me how they had my details which are on the letter if I don't exist in their system. License has changed since then but not the address which is on the letter. Should I be concerned? How is it possible that they have my details to send me a letter but can't find me on their system?
