Telkom lying to clients and robbing them their money

Telekom is far the worst company I have ever come across in my life. My heart is very sore in a way they have treated my late Mother's case. From early 2019,Telkom has been debiting money from my mother's account for her prepaid land line even when they were told that the line is not working. They kept on promising that someone will come and fix it but no one did. After more than a year of debit, June 2020 my mom called to request a cancelation and a refund, they said it will be canceled the following month and refund will be processed after that. August it was not canceled and they debited again. She called again for a followup and they promised that this time it will be done. Same thing happened every single month even after the constant followup until she passed away in February. Her refund was never issued. I have all the reference numbers for her calls and disputes. I feel like what Telkom did to my late mother is a ******** act. They took her money even after she requested them to stop and they didn't want to refund her until she passed away. I way telling their agents who were selling me Fibre deals that I'm actually shopping for one, but I will never give Telkom any business after what they did to my mother. And I will warn any one who cares to listen that Telkom do not care about their clients. My mother has been a trusted client for Telkom for years, she didn't deserve their treatment.
