Telkom Cancelation - Being threatened

Good Day I cancelled my services with Telkom in December of 2023 via Email due to relocation after Death in the Family and they never repleid. Then at the end of February 2024 was the first time I was able to go to the Telkom store to speak about the bills I've gotten for January and Febuary 2024 because I canceled in December of 2023, the person that helped me said that they never got an cancelation from me so I canceled again. I moved on the firs of January 2024 and have not been using Telkom sevices since end of December 2024 but now they are threatening me and want to take me to court due to 3 Months payments in arrears Jan, Feb and March 2024. I dont think it is Fair that they want 2 months eksta payment for a service I did not receive and it is not my fault that they did not reply on my email cancelation. I can forward the email witch they said they never received. Please can you help me with this usue? I dont even have food in my house due to renting tariff wich we never paid for before January of 2024.
