Paid off but still being charged

I received a call from Mpho on Tuesday and he promised that it will be sorted and take up to 48 hours, I called the customer care 4 times, 3 times did not speak to anyone but was requested to rate a call that I was not part of, the 4th call which was answered by Amanda who was very rude, placed me on hold for more than 15 minutes and came back confused and very rude, hanged up a call on me without a resolution, requested to speak to her supervisor she advised that her supervisor will call me next week not sure which day. I asked her to escalate to a supervisor who is on she said Kerry was on duty and she will ask Kerry to call me, not sure that will happen.

I hate the fact that she told me that she has other customers to assist, yet she showed no interest in assist me.
