APPALLING PATHETIC problem resolution capabilites with a DON'T CARE attitude

MTN did a 24 month contract renewal on my MTNChoice 2GB data plan in March. I have been unable to use the SIM Card/USB ****le ever since and NO ONE can fix the problem. Yet MTN happily debits my bank account every month for the contract fee. They cannot even process a SIM swap for me because someone loaded DUAL CALL on my account with some MTN Cell phone number that I do not know and did not request, and this blocks them doing the sim swap. I cannot cancel the contract without almost 2 years of penalties - I have tried. So I am stuck paying for a contract for a device I cannot use. I have spent over 10 hours on phone calls to MTN being passed from operator to operator - from dept to dept and NO ONE knows what they are doing or how to resolve it. I have visited 2 MTN stores as well and still no resolution. It is actually such pathetic service, I cannot even believe it is possible to get worse.
