No, they don't. At least the person on the end of the phone does not have a choice, it's there job. If they don't they get fired. They will probably get fired anyway, because these companies treat people like dirt and put them under a massive amount of pressure with impossible targets. So yes, the company chooses to call you, but the poor sod actually making the call has too call you, it's his job.
No one likes cold callers and i hate companies that do it, i completely agree with your sentiments. It drives me crazy. But note the word 'companies', it's the company you and i should have a beef with, not the employee. If i was angry with PC world, i would not walk into the nearest PC World store, grab the nearest employee and just abuse them.
Everyone is trying to earn a living, and to take jobs doing this is not a nice thing. You have to understand how this industry works. When i worked in a cold calling centre as a desperate student we did not get a basic rate, it was purely commission based. The outcome was that everyone usually earned bellow the minimum wage. Unbelievable, but true and that how virtually all the industry works. i averaged about £12 a day. If you have a nice job and good income, you probably don't know what it's like down that spectrum of the employment sector.
For christ sake people, have a bit of humanity.Try and separate the individual low level employee from the company. Be a bitch if you want, just remember it's not the dude on the phones fault, his is just trying to make ends meet doing a crappy job. If you are really that bothered, track down the company (just talking to the salesman for a bit will do that) then do a bit of research, phone the highest person to can find (preferably board member level) and give them the crap they deserve. Even more better, find out who they are, get there phone number and have some fun with them Don't get me wrong, some people in life do deserve the crap. But 99% of telesales employees don't need any more grief in their life.
Saracen, just out of interest matey, what do you do?
