As a person in sales and as a consumer, I totally get that you will make calls to gain new business or receive calls to become a customer.  However, my pet peeve (an I have plenty) is when a Telemarketer calls you and then when you ask them where they got your cell phone number, they hang up on you.

That makes my blood boil.

Come on what are we in kindergarten.

If you have the balls to call me to start with at least have enough to answer my questions.

And then when you call the number back it either goes to a recording that gives you zero information or the line rings busy.

An the Telemarketers as so sneaky, they call from a number that seems local, for instance the one I got yesterday from 406-371-2027.

Really if you call, have the courtesy to talk and respond.
