Worst customer service from MTN

Worst customer experience I ever had with any company. I lodged a dispute with regards my account on 02/03/2021 and spoken to the supervisor on duty Rhine Pillay, whom gave me my reference number and said that he escalated the dispute. He said someone from MTN will contact me within 72 hours with regards this matter and guess what...I am still waiting. I have also send him an email confirming what we discussed telephonically and also to date am waiting for a response from him. I find it shocking that I have been an MTN customer since the inception of cellphone services in South Africa and this is the treatment that you get. They are very quick to contact you with new contract offers but sadly pathetic to resolve my dispute. If I do not get a response from MTN by close of business tomorrow 09/03/2021, I will take the matter further and contact Carte Blanche to assist me to get my account dispute resolved.
