Just to confirm my suspicions I rang my computer man who said that no-one from Microsoft would ever contact me by phone.......
To cut a long story short - sure enough 'Victor' called the next morning at 8am whilst we were still in bed (keen or what?)

He wasn't taking no for an answer even after I called him a "con man/fraudster" etc, he said he would call back in an hour or so

I wont repeat what i said next but he didn't call back...someone else did

Heard no more since
