I am going to go into that as well, but working for someone in the actaul centre. Some of my friends said no, but some said yes, I think it depends on who u go to.
Be careful for those telemarketing jobs where you get paid commission/ retainer... you only get paid as much as you can sell. It might end up not paying much. There's a girl who went to my school, she's doing telemarketing, but they pay an hourly rate- $20, which is better.
I remember at my friends house, her mum would fully get up the telemarketing people, cause they would keep ringing her even when she told them to take her off their list
