lack of response

I purchased bundles from MTN when I noticed that my data usage was not making sense I then called 173 and spoke to an advisor, Mandisa, who could not tell me what was going on. I then requested a supervisor. After 20min of holding I then spoke to a supervisor who could not answer my questions either. Instead she gave me information that did not add up as well as denying the disappearance of data after MTN had rewarded me with 60rand free airtime. I have been waiting for feedback from MTN and still haven't received any. Instead I've been told to request itemized statements which can take up to 2 weeks to receive. I have had enough of the poor service and inconsistent information along with thr ddisregard I have received.
