I had one this morning that just wouldn't take "no thank you" for an answer...I have had the same group call about every month...and my answer is the same every time...no...
I finally decided to bend his ear....told him that the dog made a mess in the house and went on to describe it in detail...lol...when I heard him start to hem and haw a bit...I finally said" I have told you no, numerous times....if you call again, I will consider it harassment and report you.
He hung up! hehe
