I get these calls sometimes 3 times a day...have asked to be put on the "do not call list" to no avail, and they are rude and hang up during my conversation. I called my phone company to complain and was told that as soon as the call has been completed (when they hang up on me), to press *60 and that should block any further calls to my number...we'll see! Perhaps there is hope for we victims of vicious and rude telemarketers!
