Phone Billing

Good day I have a problem regarding our contract which was undertaken by our father. He pensioned in 2023 and subsequently requested a full quotation of the phones he took for us. He was given the quote and paid the phones in full. However, the agent who assisted him did not cancel the contracts after he paid the remaining balance of the phones. We queried this to Mtn and they said the matter will be placed under investigation. Every month my Father had to go Mtn Welkom branch to get the phones switched on. They even insisted that they will reimburse us the money we had paid before. In the month of December the company insisted he owes R9000 and has subsequently switched the connectivity of the phones. It’s January now my siblings needs to go back to university but none of the phones are working.
