Thanks for that info;my cousin who is now retired was scammed recently.They claimed(foreign accent) that they were from Microsoft on this occasion and had found "problems" on his computer.To put this right they needed to get into his computer,so he gave them his details etc to allow access,then charged him ?150 to "put it right",which of course he paid with his credit card!!!
He didn't think much of it,then they 'phoned again the next day to ask for more details,which he gave them.Then his daughter came to visit and when he told her what had been going on,she realised he'd been scammed,and took steps to prevent any more damage.They had the nerve to phone again and he told them he'd changed all his details,including his credit cards.
The emphasis here is to say it can happen to anyone.My cousin is a retired Dr of Science,with three degrees to his name,intelligent and lucid,and he was scammed.
Don't ever give anyone any details for any reason is what I would advise.Keep asking questions of these
vile scammers,and they soon go away with nowt,and usually a very big flea in their ear from me

Incidentally,he tried to claim on his insurance,but because he had willingly given out his details,he got nothing.Be aware and warn others!
