All along I have requested these callers to put me on their do not call list but it doesn't help so I am on a mission to piss the callers off as bad as I can and it seems like it might be helping. My latest gig is to let them get a head start on me and then interrupt them after a while and ask ask how long this will take. Just a couple of minutes is an almost guaranteed response so I say ok , Then after a couple or more , Depending on the call I say ok stop I gave you the time you asked for and I am done. WOW for mad. I think I get a check mark or a note next to my name something like "Don't bother calling" . Unless it goes in a cycle or something, It's going on 3 weeks now and I was getting them several times a week.
