Incorrect airtime amount

On the 26th January I contacted your call centre and spoke with Zoleka Ngcobo, I asked her to load me airtime for r100, while I was holding an sms came through confirming that loaded R335 of which I must pay month end and its unbudgeted for. Unaware that I received an sms she the. Said she loaded the airtime and I told why R335 then only she apologized meaning she was going to lie if I never received the sms , I asked to speak to her team leader who never called me to this day I got cut off I called again and spoke to Lindiwe who said the team leader is Makhosonke and she will call me because she is busy with an escalation to this day no call. So I would like Telkom to reverse that amount because I can't pay R335 more month end and Zoleka said she will pay it herself but to this day she has never called me can someone help and atleast call and explain or take responsibility, Telkom debit our accounts before payday we get charged bank fees and they don't want to stop their perverse behavior and giving us bad service
