Cold calling and an angry customer

Some calls may be recorded or monitored for training purposes, and thank God they're monitored so we could have a laugh at this. I don't know if I want to be that British Telecom guy that rings and wants to sell something. This is how cold calling should be handled, I mean don't you wish sometime you could just start cursing the same way as the customer below does?

 

Just to remember the fun of it I've also transcribed the discussion:

customer: what the hell do you want?
speaker:mr and mrs carter
customer: what the hell do you want?
speaker:we're calling today to ensure you're getting the best value in service, British Telecom have got an offer...
customer: put this fu***** phone call up your pis**** ar** and get me off this. this is an ex-directory phone and that includes fuc**** British Telecom
speaker:ok
customer: we pay the fuc**** bills now get the fu** off my phone line, DO YOU UNDERSTAND?
speaker: i understand sir but...
customer: good, well make sure it's fuc**** written down and don't ring me again otherwise i'll come and ring your scrawny fuc**** neck and i mean physically
speaker: no problem
customer: do you comprehend?
speaker: yeah sir, all it takes is a couple of seconds
customer: I TOLD YOU TO GO AND FU** OFF, DO YOU COMPREHEND
speaker: yeah, thank you for your time
customer: GOOD, DON"T EVER RING AGAIN
speaker: right, thank you for your time then sir and thank you for using British Telecom. [hangs up]
speaker: Jesus Christ Diane. Could you do me a favour and listen that last call for me please?
