Have been calling me during several months, always from " Windows maintenance dept. ".
They want to fix servere problems in my PC.

I have been getting calls from very strange numbers that are not even in my area code location and do not want to be receiving calls from these people any more. I worry that I am getting charged for every call that comes my way even when I just check the messages.

Got a call from this number and said that I won a grand prize, to press 9 to see what I won.
