Lack of transparency

I have a contract with MTN account number A*** with two mobile phones on it.One account ends with 2411 and 7027.We requested MTN on numerous occasions to email copy of contract that ends with 2411 since we believe that contract ended already in March or April 2024 and we are still paying the same premium for the contract that ended. Furthermore we requested a detailed statement of both contracts since the inception of the account as MTN claims we are owing over R4000.00 that is in arrears.We requested that to see where we missed the payments so as to rectify the missed payments if we are at fault. We send through emails and got reference number REQ*** and REQ*** till this da 18/9/2024 we have not received any feedback from MTN. I believe they are acting in bad faith and taking us as customers for granted or because we don't complain they think we are stupid. I cannot pay contract that ended after 24 months and still pay the same amount because as per our understanding the 2411 account contract has ended so they should be billing us for the units and data not the instrument. I hope you will be able to assist me on this matter as we have been send from pillar to post for just requesting a detailed statement and copy of the contract.
