A friend and myself were saving money in my savings account on a monthly basis by standing order for a set period of time. Due to change of circumstances my friend had to stop sending money into my savings account, and informed his bank to stop the standing order.
After some months he noticed that they were still sending the standing order (I hadn't noticed as it is in a passbook rather than an online account). He then rang them up and they admitted they had a record of him requesting that the standing order be halted. They credited him with the money they had sent in error.
His bank have now written to me requesting that I send them the money back, but I am perplexed as to how they have got my address details as I am not a customer of theirs and my friend has not supplied my details. I suspect that the building society that I have my savings account with have supplied my details to my friends bank. Surely they have no right to pass my details on and should have written to me themselves?
Have any laws/codes of conduct been broken by my friends bank or indeed my building society, and if so what, if any, route do I have to complain?
What do people advise?
