I do sympathise, honestly. I don't like getting these calls much either. Most telemarketing places are really badly run on tight margins/shoestrings. "Training" is usually a joke in these places - it's more often a lecture/punishment for not "trying" hard enough on the phone. Callers are usually bullied/pressurised into being "pushy" to get anything like a decent wage, and in many cases just to know they can keep their job.
And lets face it, if they were actually good at sales, they wouldn't sound "pushy" ... thats down to the piss poor recruitment and training/support you find in telemarketing operations.
