MTN DOESN'T NEED MONEY OR CUSTOMERS

I have been due for an upgrade since September 2024. I spoke to three different consultants in connection with my upgrade. Every single one promising to phone me back once the upgrade has been processed, still waiting on those calls. I phoned the contract cancelation department yesterday, and spoke to Nzuzo Christian Cele. I wanted to cancel the contract, as I'm not getting any service from MTN, and there is another price increase in February 2025. The consultant gave me a great deal, 15 Gigs of data and 525 minutes. Which I wanted, and agreed to upgrade. Nzuzo promised to phone me back as soon as the upgrade has been processed. Needless to say, I am still waiting on any call or feedback. Is it so difficult to do an upgrade??? If anyone from MTN could just contact me, this can be sorted out.
