MTN South Africa (HORRIBLE SERVICE) Contact Centre, SME Department, Banking department)

My experience is horrible with MTN. I wanted to make payment on my Mtn account, I called the contact centre for a consultant to assist me in making the EFT payment, the consultant gave me the incorrect details. The payment could not be allocated and my account is now reflecting as arrears for the past 4 weeks. The banking team has not resolved my matter even after calling in numerous times, I am still waiting for a manager or team leader to call me back. I am highly irritated and upset at how MTN is dealing the matter. It’s not right and it’s not fair. I just need for my query to be resolved. I am not understanding how does MTN deal issues like this?
