MTN good to take your money but not good at providing customer service

On the 1st of March, I received an SMS Notification to confirm that an outstanding amount of R580.27 was due on my account and I should go in-store to make a payment. Which I did, the same evening an amount of R800 was debited from my account. I then contacted MTN to escalate this matter, I was then told that the above SMS notification was sent in error and they will reverse the amount of R580.27 which was paid in-store. Over the course of this week 15 March, my account has been suspended twice. I have contacted MTN and on each occasion, the consultant confirmed this was done in error. I have obtained references for each call. As of today, I cannot purchase data via the MTN app, nor use the free airtime minutes as per my contract, it's also deducting monies from my fixed airtime amount. How many times do I need to contact you guys in order to actually unsuspend my line and utilise my contract?
