Hi! I have put the phone next to the radio as well.. I just like to block their line and waste their time like they waste ours.
We had the one the other day where they act as if they are from Microsoft and tell you you have a problem with your PC. You know the one - they tell you to switch on your computer and follow their instructions? They like to target older people. If you fall for this and do it, you end up creating a real problem -for which they then sell you the solution!
Well, my husband took it. He works in IT, so was looking forward to wasting her time. She told him there was a problem with his computer, so he said Oh Dear etc etc, what am I to do? She told him to switch on the computer.. he asked her which of his computers had the problem and that he had six. Should he switch all of them on? Then he told her he had a good idea - if she gave him the license number of the computer she meant, then he would know which computer it was. She said she would know because there was a light on her board which showed our computer was faulty... he replied, oh but I haven't switched any of them on yet. (Yawn, yawn by now...)
Well, I just sat on the stairs and laughed and laughed. He kept her at it for a good 10 minutes before he 'decided' to take the computer to his usual repair man and put the phone down on her. She was still bleating on about it would have to be at his own risk because only they can help!!!
But you know, the worrying thing was that these people do sound so credible and it is easy to see how the older and less savvy can fall for the scam.
