I let them throw their spiel one day, guy named Charles Edwards. He was new so he wasn't pushing the sale too hard, it was a pleasant enough conversation (Of course I kept saying no). Then his "manager" came on and tried one last time, he was a dick, convo done.... Think not, I get a call about 40 minutes later from the same area code and let it go to voice mail. It was the first guy I had been talking to and he said he enjoyed talking to me so much he called me from his personal number!!!! Sent me some weird texts wanting to be fb friends etc. (11 yrs older btw). I threatened to tell his company and it finally stopped. It was really creepy.
Don't bother answering!
