Cellphone contract

No one is willing to assist me with my account. I am under debt review. I'm willing to pay my outstanding balance over a period of 4 months. The person that helped me to open the cellphone account **** to me. She told me my old contract will expired, closed in December 2022 & then by January 2023 I will only pay R300 for the new contract. Now I fount out I'm paying R700 & they refuse to assist me. They even blocked my cellphone number when I called the call center. My current bank account is not active but they still run debit orders through on that account. The service of the 3 people I spoke to was utterly unacceptable and very annoying. They have no phone skills or people skills. They get upset if I ask questions. I need a telkom account number to makes my payments. I hate telkom service. Can anyone help me. If u can't assist me, how do u assist people that's unemployed and want to pay. Can someone please help.
