The best way I found to deal with these calls is to make a note of the number, then when you see the number on your CID, pick up the receiver nad immediately hang up. Somehow this seems to remove the number from their data base. Of course, when they start with a new number, you have to use the same technique again. I now only get about one or two calls a week compared to several per day. Hope this helps!
on november 15, 2013 we received an obnoxious phone call from a guy soliciting for seo-type marketing products. the caller insisted that it was not a sales call, he was not well-trained, quite impatient, and said he was with google. we work with google all of the time through our business and have nothing but respect for them.
we asked that this guy remove us from their call list and the caller than called my wife a "f***ing b**ch and hung up.
