Male, very rude, trying to act professional in asking for my boss.  When I asked who was calling please, he brushed me off and acted as if he was talking to an associate sitting next to him as if to sound professional. I asked again "who can I say is calling"  he replied "yes, yes,  I will hold for him" and continued to talk to this other person. Totally ignoring me.  First thought was to hold until he stated who he was, but I reluctantly gave my boss the phone,  He was just as rude in trying to sell his goods, not taking no for an answer and belittling and abusive in his insistance that he could possibly do us any good.  Even after several " no's" and "do not call us again" my boss finally had to hang up on him.
What will they come up with next.  There should be some kind of law against these cold callers. Especially the rude ones that are full of themselves and bully their way into your business.
We both had a good laugh about it afterward.

Wow! These people called our business 5 times in 3 hours today.  Finally I answered and said "could you please take me off your list?" Guy goes, "you don't even know what I am calling about!" I let him know that because I have gotten 4 calls already from HIS number, that indeed I did.  Was rude.  Kept asking for a manager employed here 7 years ago.  May want to update your info if you want to appear less obvious that you are an annoying TELEMARKETER!
