MTN FAILING TO ALLOCATE THE ACCOUNT PAYMENT MADE ON THE MTN APP

"My Mtn App" payments are totally useless. ??? My MTN account***) was due on the 2nd of August 2021. I made a payment via the MTN app to my account on the 31st of July 2021, right on time. On the 10th of August, I realized my account had been blocked. I phoned the MTN call center to query the matter and they told me the transaction hasn't cleared on their system. ???I told them the transaction only takes 3 days to clear and it was the 10th day. They then demanded proof of transaction. I sent through a proof of payment from my bank confirming the transaction. I was told the matter had been escalated to the finance department and it will take 3 days. Today the 14th of August my account was blocked again. I phoned the call center again and the agent told me the payment doesn't reflect still and the person who logged in to my previous query sent it to the wrong department. Imagine the level of incompetence!! What's even worse she told me my account will be unblocked but only until the 20th. Imagine the frustration. The question is why make a payment method available if you cannot manage it? The app payment automatically detects the phone number linked to the account and doesn't give an option to edit a reference so it should be easy to allocate the payment. I'm very ****ed. I'm treated as if I made a late payment and it's like I made some sort of payment arrangement whereas I paid on time!!! I've been a loyal MTN contract customer for more than 7 years and I've always made timeous payments only to be treated like this. If you list my payment as a late payment on the credit bureau I swear I'll explode. ? I'm reporting MTN now because they are dragging the Matter!!! I don't recommend MTN to anyone!! MTN SORT THIS OUT!!!!
