Query not resolved

I purchased airtime via atm twice using absa bank and it did not to thru. I queried with the bank and they advised that the issue was not on their side. The consultant at the bank want as far as contacting MTN on my behalf and sending them my query. We spoke to Nqobile Ndlangamandla from MTN who promised to escalate the query after we forwarded her the bank statement. I called MTN the following day for feedback and was told the consultant is off and they cannot resolve my query. I even spoke to a supervisor who was not much help because they kept making excuses. A simple atm purchurse has consumed too much of my time because of MTN. I am thiking of changing networks as it is.
