Appaling customer service (twice!)

I have been trying since last week to get authorisation for an early upgrade, but it seems that there is no-one in the entire universe who can actually do this.<br> <br> I first phoned customer service, was redirected to ***, was again redirected to customer service who directed me to ***, who were unable to help me.<br> <br> I asked the sales consultant to escalate this to her manager and was told no-one was available to assist.<br> <br> So, in short, I earn MTN at least R2,500 per month in income and they are more than happy to take my money. When I try and get something from them no-one can help. <br> <br> I then sent an e-mail to the complaints department and lo and behold - 4 days without a response.<br> <br> I can't believe that a company like MTN can treat customers like this.
