Perhaps you can clarify the issue , first , are BT your provider, or do you think it’s BT’s responsibility to sort it out regardless of the actual provider ? ,
if your neighbour (new neighbour presumably that’s recently moved in ) put your address on their application for service, you should have received a communication from your provider saying something along the lines of ‘sorry you are leaving’ , did you get anything like that ? ,
who is your neighbours provider ?
if your address were incorrectly used by your new neighbour, then you would expect their service to be now ‘live’ at your address (even if you can’t use it ) and them to have no service at their address , because it was incorrectly supplied to your address , is that the case ?
Is it understandable why someone could mix up your address and their address, like they have the same house number but different suffix, like 1A and 1B , or are they very different although likely to have the same street name , perhaps you can give the first part of your address and their address , obviously don’t provide any personal information.
