Well you could be in luck. There are a load of Call centres springing up here all the time. I work for one! Not sure if we've got anything available at the moment but have you checked out a job website called Career Junction? They have quite a few roles in call centres in Durban. Companies you may want to look at are Rewards, Blake International, Unlimited World.

Can't personally recommend any as I don't know enough about them but if you're really keen on moving over then they are places to check out.
