Not that my faith in BT is what you'd call unshakeable, but if it makes you feel any better, it's highly unlikely that there's any connection. Scammers call literally thousands of numbers every day, and it's just the law of averages that now and again one of those numbers - yours, in this case - will happen, by pure chance, to overlap with a genuine fault. Since all scammers spoof their originating numbers, unfortunately, any number that appears on your scanner is meaningless. As a general practise, if callers claim to be from generic sources such as 'your internet provider' or 'your phone provider' or 'your bank', the first thing to do is ask them to give a specific company name. If they claim to be from BT, asking for their E.I.N. ( employee identification number ) will usually result in the call being ended there and then. Also bear in mind that once again, by the sheer law of numbers, if they claim to be from, say, NatWest, for some percentage of the time they're almost certainly going to be right. If the call is unsolicited and / or unexpected, tell them that you're going to hang up and call the fraud department of your own bank / internet provider / phone provider etc. to verify that the call was genuine. If they hang up there and then, it's a safe bet that it was a fraudulent call; if you want to be sure, then do exactly what you've just told them you'll do, using a number that you know to be valid ( for example, the number on the back of your credit card ), rather than any number they may 'helpfully provide'. In this eventuality, always leave it a good four or five minutes after having hung up from the original call before you dial out again.
The bottom line is, if in any doubt whatsoever, never do anything they ask you to do with your computer, and absolutely never push any buttons on your phone.
