Incorrect Billing and Upgrades Failures

I app**** for the upgrade on 29th December 2020 online via website. *** In January I still receive my same of my previous contract which is a 100gb + 100gb Black Friday deal for R469.00 which I paid for. However later the month a got an sms and a statement stating I still R1200+ because my previous deal is out of contract. I demanded to speak to your Manager named “Ryan” from Accounts department and informed him about this which he could not do anything. He told me to go back to the agent to lodge a ticket to resolve this issue. Then my number was deactivated for no reason. This is cause me to loose clients as I am a Project Manager for a building company. I immediately contacted the agent at Promenade Branch to enquire about this. Waited 3 hours before the consultant assist me. Which I had to sign a day-off from my leave. The agent then logged tickets about this and to this date there is no resolution. As it now my accounts stands at R6475.43 which I’m not paying for. The amount I should pay that is outstanding is R597 which is R199 x 3. Which i paid.

Ticket Reference numbers & date • *** – 05 March 2021 • *** – 01 March 2021 • *** – 03 February 2021 • *** – 22 January 2021 • *** - 24 December 2020

I have sent an email on the 12th March to *** and to date I haven't received a response. On that same day whist on the call with the same agent from store, I app**** again for the same data deal on the website. ***

I am just so annoyed that being a MTN Customer for so long and no one can attend to this issue.
