MTN allocate me the promised package or return my money.

I signed up for an upgrade with MTN direct via their retentions department. Kwanele Mncube is the agent who dealt with my upgrade. Came the provisioning,I got nothing agreed upon. I have sent about 50 eamils to customer care. Sent about 20 messages to messenger, I believe they have blocked me now. Sent an email to some top management person named Pat Mamane. No one could be bothered to respond. I have requested to speak to supervisors. I was promised that they would call me back. Then they went and tripled the debit order amount that they were supposed to debit. They ignore my demand that they retrieve the call recording and allocate to me what was promised. What a bunch of *********** ******* who are now *****ing my money. Let us hear their damned defence.
