Please help me with this matter I will be highly appreciated.

This is getting out of hand and makes me angry. On first of January 2022 iv called your call center asking why they dont debit money on my account because I have a contract with you guys and the lady said is holiday I should wait until 2moro which is the second of January 2022. But still on the second money was not debited I called again and the lady said already the on the system says it have been debited I should wait for 2day so that it can reflect on my bank account. Fine iv waited but still the money was not debited. On the 4th I called again and spoke to Ellen she said she will take the matter to her management team and she took all my details promised me that her management team will call me back but still I didn't receive any call. And on the 5th I called again I dont remember the guy I spoke to he also promised me that his management team will call me back and there name are Nonhlanhla or Golden I should expect the call around 8:30am in the morning still I didn't receive any call. Around 12pm iv called again and the lady said I should query with my bank and I can go to any mtn strore. Well I went to bank and they've checked my account it doesn't show anywhere that you guys tired to debt and you didn't get money. I went to mtn store in kollonade where I didn't even get any help a guy by the name of Jean he was telling me that I need to go to Menlyn to query about the matter if ask to speak to his manager but his manager by the name of Vusi he refused to speak to me and said his busy.

But my bank statement says the was money in my account and you guys didn't even tried to debt because it doesn't even show anywhere that you tired to debit so I'm not going to pay extra 11rand for you not doing your job I will never this is my story please Help hello peter
