7 Months and not even a reply to my e-mails - 7 Months and my case is not resolved - Disgusting

In December 2020 I upgraded by phone. My new monthly premium is R439.00. For some reason MTN kept making a mess with my account, the wrong amount was being debited, then the wrong date was used for the debit order and then they constantly cut my line even thou payments were made. I eventually cancelled the debit order and did EFT payments but they still continued to cut my line and i had to call in all the time to get the line un-blocked. I have spoken to call center agents who are honestly so useless and ***********, sent emails and still no responses and am no at a point where i just want to close of this contact and move on, there *********** has resulted in my ITC being negatively impacted and no 1 can answer for this...you guys are really disgusting and i want a person in senior management to get this matter resolved, its 7 months now down this road and not even a call or response from MTN absolutely disgusting
