Disappointed and Unhappy with MTN Systems

I was up for upgrade 22 July 2020 as per the upgrade functionality on the MTN website. I get to the shop I'm told its now August. When I check upgrade legibility via sms it say August, on Mtn website its July. I'm told its some new system.

Now I took a health risk to go the shop knowing I'm up for upgrade and I need a phone. To avoid going back to the shop in August (Lord knows how many Covid Cases we will have by then); I had to do early upgrade at a cost. It is unacceptable for me to loose money because MTN systems give me 2 different dates for upgrade eligibility and the latest date is new to me the user who was not even sensitized to this effect.

As if that is not enough! I was owing MTN 4700. I go pay at the shop and I'm told I owe R5900. To avoid my line being suspended and me being threatened with contract cancelation; I pay. I query this and the friendly customer care agent informs me that the balance will be deducted from my next statement. Today I'm sitting minding my business and a debit order of R4700 is deducted by MTN. I made no arrangement for debit order of R4700. Now R5900 and R4700 has gone to MTN. As a result the payments I was gonna make elsewhere with the R4700 are impacted. What kind of a system deployment has to be so inconsiderate to customers.
