Phone help required
Not quite a computer issue but I'm starting to get suspicious.
I have a couple of mobile phones, one for my wife and one for myself.
My wife keeps receiving calls from a number that she doesn't know. She answers and says that they have the wrong number (no actual responce on the other end of the line) but they keep calling. If she doesn't answer they leave a message that is blank/background noise and call again. She is now at the point of screaming down the phone.
I've called my phone company and they say that they cannot block the number.
Any idea what we can do about this? (I'm in the US by the way)
