i regret signing a contract with Telkom

I wonder if Telkom cares about the frustration they cause. I have cried and cursed all because of Telkom. In July 2017 I ordered a fixed uncapped internet connection. It was installed with the d-link modem provided by Telkom. I had 6 days of connection And then it died. The Telkom technician said that Telkom provided a faulty modem and that it must be replaced. In store, I am informed that it will be sent for fixing and will be ready within 21 days. I have not been told to collect it or that it's fixed. The shoddy helpline consultants says there's no record of a fault. Your call centre service stinks. I paid for two months of connection yet I have only had 6 days of connection. When will I get the help I deserve?
