MTN issued invoice only days before debit order and closed dispute without fair review

I am extremely dissatisfied with how MTN has handled my billing dispute. MTN consistently sends my monthly invoice on the 19th or 20th of each month, while the debit order runs on the 25th. This gives me only 5–6 days to receive the statement, review it, identify any irregular charges, and lodge a dispute before the money is deducted. In my case, I was not warned in advance about excessive out-of-bundle charges, nor was I given reasonable time to prevent or dispute them before the debit order date. By the time I received the invoice and became aware of the magnitude of the charges, the debit order was imminent. I raised a formal invoice dispute with MTN (Case number: BO***). However, instead of addressing the issue of insufficient notice and lack of proactive alerts, MTN simply stated that the charges cannot be reversed and then closed the matter, offering only to cap future usage. Closing a dispute without properly addressing the fairness of the billing process is unacceptable. Issuing invoices just days before debit orders does not provide customers with a reasonable opportunity to act, and this practice places consumers at a clear disadvantage. I am requesting: A proper escalation and review of my dispute Consideration of a reversal or goodwill adjustment An explanation as to why invoices are issued so close to the debit order date I am posting this here in the hope that MTN senior management will intervene and resolve this matter fairly.
