I am fed up of receiving calls from unknown numbers. Particularly telemarketing callers who almost always call at inappropriate times. When I call back, it is almost always that a machine answers. I have now decided to report every number to Who Just Called Here so that others may also know. Recently I was reading a comment from a user of the site who had reported a number from a collection agency. The caller was very rude and talked to him in a contemptuous way.
