Bad Service as Usual

I have a contract with Telkom, I am supposed to payment R849 for my device. In August I changed my banking details, I called Telkom to provide my new banking details, to ensure that the debit order runs from the correct account on the next debit order date. The debit order never ran, I called Telkom again to find out what the issue was this time! I was told that the agent I gave my details to FORGOT to SAVE my new details, as a result the debit order went off my old account. The agent I was speaking to at that time, merely apologized and said she would save my new banking details, FINE. My account has now been debited twice 1. R1200.25 – 27/11/2017 2. R1125.00 – 24/11/2017 I sat on the phone for 30mins with and I have no received any explanation regarding the debit amount.
