Although I have not had an account for about 3 years, I recieved a letter to my address but with an unfamiliar name. Thinking this may be some scam - someone taking a phone contract for example - I rang BT. The call was answered by the Indian call centre staff (who were very polite) but sadly they really couldn`t understand what the problem was. (Indian call centres were the reason for leaving BT 3 years ago).
I emailed the CEO - but they wouldn`t tell me why my address has been linked with someone elses name - just blaming the marketing dept. This is unnacceptable as your address allows companies to identify you and link you with your financial behaviour.
