I received a letter with BT logo stating that I have requested a copy of the information BT held about me. I did not. I rang BT and was told it is a scam and to ignore letter since they have not sent any. Not sure how this scam works but be aware!!!
Just for info, was the letter addressed to you personally, and maybe showing an account number or other information?
What was the jist of the wording of the letter? Were they asking you to contact a phone number, and email address - and were they asking for money?
