Christmas Gift to Myself: Get Rid of MTN

One star only because the system does not accept no stars. I've had 2 MTN accounts for some 10 years. My wife persuaded me to renew her contract against my will 2 years ago at MTN Bayside. At the time, I cancelled the other one. Various problems with roaming and other services while we were travelling. Today, we went to MTN Table View Mall to get the roaming sorted out. We were told the other contract had not been cancelled. The agent put me through to the call centre. Discussion. Then I was asked to create a PIN to avoid going through all the security questions again. But the next person insisted on asking all the questions, anyway. And meanwhile, the agent in the store almost laughed her head off at my frustration. No way this contract is going to be renewed.
