Account incorrect suspended

MTN Account No A***

My account has been suspended for the past 6 days due to a billing error at MTN`s side. I have sent numerous emails to customer care, collections and social media escalations but there is no response and my data and voice remains inactive. I have attached proof of payment for the past nine months and still, no response and no activation. There is no service agent when you call 135 and the MTN stores advise me to send emails or call customer care. How does one resolve a query that has been going on for 4 months now and your data and voice is suspended for 6 days? I am losing income because of this and my employer gives me 24 hours to sort out my personal challenge... but no one at MTN is correcting my bill, allocating my payments, bringing forward my credit and lifting my suspension. I am a loyal paying customer for the past 12 years and paid every month my account even when MTN suspends my account every 2 weeks because of the billing error occurred in April 2020. I request my account to be corrected, proof of payments allocated, my service reconnected and any liabilities removed. Please call me and advise me that me account is sorted. No one is calling me to advise what is going on. I only find out that is still incorrect when a triple deduction via debit order goes off and my account again suspended because no one corrected my account after all the emails and requests over a 4 month period
