Hi I just got a call from BT saying that my IP Address has been changed from private to public and that people are using my internet. I have no idea if this is real and I didn't feel right with the questions they were asking so I hung up. Would this really be BT or some sort of scam?
BT will never call you to tell such rubbish. If you get any other unsolicited calls purporting to be from BT just hang up. BT would not call you out of the blue to tell you that you have a problem with anything to do with your computer or broadband.
