Telkom doesn't care

On the 24th Nov 2020 I was signed up for a data contract by one of Telkom's sales agents. I was informed that I would have a SIM delivered to my home within a week. I was also told that my bank account would be debited in order to test the account but that the debit order would be reversed immediately as my first payment is only due at the end of December 2020. To date, Telkom has taken my money but have not reversed the debit order and I have still not received my SIM, which I require in order to do my job, which I started on the 1st December 2020. I have not been able to work and therefore have lost income and now I stand to lose my contract. Is this what Telkom thinks of their customers or is it simply because the contract I took was small money and therefore I am considered insignificant? I will not recommend any one take a Telkom deal, no matter how good a value deal it may be. The service is pathetic and they simply don't care.
