lol.. If these call centres end up with people working there with the same mentality as the people who work for Telkom, then I'm afraid the Brits will have a bit of a surprise ;P
Obviously, the correct training is essential in the call centre environment and the more callers that call into a particular call centre, the faster the training needs to occur to keep up. Short circuiting the process leads to frustration for the people calling the call centre who bump into the "newbie" operator.
One has to visit India and China to know what is happening in these countries. It is not about bandwidth and English.
"For example, because credit card use in Bangalore is limited, a bank in Britain would first have to train the call centre agents there about their use, whereas SA's banking system is advanced." I could not stop laughing. Someone, somewhere in SA does not know what is happening in that part of the world.
