I was called by a lady from this number at 08.57 am  telling me I had something wrong with my computer.
she was advising me to press certain keys (obviously so she could obtain details from me).

So I played dumb and said I'd like to chat to my husband first and then can I call her back  and so could I have a phone number,  she gave me this one.   I said there was no such number in the Uk and she said she was phoning from Florida. !!!!
That means she was ringing me up her time 4 am.
