MTN as a service provider sucks BIG time

2 x payments made on 8 September 2020 (R629.09 and R299) for my 2 contracts through EasyPay have not reached my account. 2 months later and MANY phone calls to the Call Centre and emails to Customer Care have been ignored. The payments are still not reflecting. A visit to MTN Head Office in Fairlands on 16 November 2020 has also resulted in false promises of "we will get back to you within 48 hours". I am out of pocket by almost R1000. My account was barred and I had the embarrassment of being told by MTN Clearwater Mall on 14 October 2020 that I could not upgrade because my account is in arrears. Surely there is someone who must be held accountable for this absolute shocking service. I have had my MTN mobile number for 21 years and this is the service I get.
