MTN stole from me over 18 months

I need urgent assistance from a level higher than the customer service call centre!

In all my emails you will find that the MTN customer service is ***********. After more than a year I managed to get into their heads what MTN has made a urge mistake. Supposed decrease from R688 to R399 increased to R789 Now that they understand, I have asked in emails that the MTN finance department pay the OVER CHARGED instalments of R7329.05 into my BANK ACCOUNT. The mistake that MTN made, to Debt my bank account with a higher amount, caused me to run into a shortfall on my budget.

At this stage and time I have to have the R7 329.05 in my First National Bank Account before close of business 20 Jan 2020. MTN has ****** from me, and this theft is causing me to suffer the loss of my assets. The Call Centre Operators and Finance Department are clueless. They don't understand what they are reading in emails. I spelled it out that the full amount has to be paid in to my FNB account. Finance department went and credit my current outstanding balance. ***
