I'm surprised they are still calling. I've not had these calls for quite a while, but when I did get them they were quite regular. Most of them hung up when they realised they weren't getting anywhere. Only one call, when called out, resorted to verbal abuse, which was quite unpleasant at the time.
I guess there's still lots of people to try and fool, otherwise i'm sure they would have given up by now.
