Pathetic accounting system, pathetic service !

Pathetic service from MTN. Paid our account via the MyMTN App on 7 April 2021. received a payment confirmation of the payment. On 14 April the phone service was terminated, MTN demanding payment of the account which was also in arrears according to the sms received. The payment via the App was not visible anywhere. Spent hours and numerous calls to the call centre to sort out the mess and the service was reinstated temporarily. Physically visited a branch but staff there had no access to anyone to allocate the payment done to the account. Got another sms on 25 Apr demanding the payment of the account plus "arrears" which has been under dispute for more than 5 years. As a precautionary measure against suspension, the full account was paid in the branch. Still no reflection of the payment via the App despite sending endless emails with the payment confirmation received attached. A few days later - receipt of two sms messages, one indicating indicating the payment received from someone unknown, the second sms a second later demanding the payment of the amount indicated having been received in the first sms. Two days later the debit order deducted the exact amount in question from the bank account !!!! Despite all the calls to the customer centre or service champions as they are called the accounting mess-up seems to be getting bigger and bigger. A multi-million Rand company with a pathetic accounting system and clearly no regard for that individual subscriber client who contributes dearly to the company being where it is !
