MTN do NOT want to perform Upgrades

I have been struggling for over ONE WEEK just to upgrade my Data Contract! I have phoned SIX different people, on THREE different days, and have THREE DIFFERENT Reference Numbers!!!! You HAVE to answer security questions from Customer Support (083 135) who CANNOT perform an Upgrade, so WHY the security questions at all???? Then you HAVE to answer MORE security questions from Upgrades department (AFTER I already answered Customer Support Security Questions already). And this happens EVERY SINGLE TIME you phone!!! And now Upgrades department demand Confidential Documents (Bank Statements, Payslips and ID) to be sent to some "Unknown" e-mail address (@cci-sa.co.za) but they CANNOT e-mail you to request the documents, and they CANNOT phone you, no matter how much you beg them!!! But they ALL PROMISE to e-mail you, and they ALL PROMISE to phone you, but........NOTHING NOTHING NOTHING!!!! They LIE, they LIE, they LIE!!! It's like MTN do NOT want my business!!! If I have to do a RICA every time I upgrade with MTN, then I might as well go to Vodacom and do the RICA anyway! Finally I upgraded ONLINE WITHOUT any assistance from any person! At least I got an automated e-mail response with my (FOURTH) Reference Number. But now I CANNOT get a copy of my Upgrade Contract!!!! I have PHONED (and spoke to FOUR MORE people), and I've also sent FIVE e-mails to TWO other e-mail addresses, just to have a reference of my Upgrade Contract, And right now, I have NOTHING NOTHING NOTHING!!!! Why do MTN NOT: 1. Send a SMS to confirm the upgrade is complete and WHAT package has been upgraded and 2. e-mail a copy of the Upgrade Contract to me????????
