Change of Debit Order Date (6 months later not fixed)

I am being bul**** by MTN and it's employees. I contacted MTN call centre to ask them to change my debit order date since from November 2018. I have been calling them every month and they show their incompetence by giving different advise month in month out. They once told me that they will load a manual debit in order for my debit order date to be changed and I comp**** to this arrangement. To this end, MTN has not changed my debit order date. This is an inconvenience to me and forces me to maintain a particular balance each month to ensure that MTN's debit order is not returned.

Recently (in April 2019), I spoke to some guy at the callcentre (named, Liciano or something), he was so cheeky with me and when I complained to him he said what he was doing was a standard operating procedure (the guy showed me a middle finger because he said "its either you comply or you jump"). I felt like I am dealing with the ANC government employee, but because the guy insisted that that was the way to get my debit order fixed I had to understand and behave. Till today my debit order date has not been changed and the ill-mannered "Luciano" guy failed to change my debit order date.

I am writing this review to register my dissatisfaction in the way MTN has handled my request to change my debit order date. Account number A **********
