31st January 2025, my 24 months contract expired

31st January 2025, my 24 months contract expired. February 2025 I called, spoke to consultant we agreed on paying R459 per month, not a contract. On the 7th February 2025,I was called by their consultant giving me 24 months price lock contract for R299, I agreed but explained that I was going to pay R459 including extra view, and she said including extra view I will pay R399, asked her many times to confirm R399 as I know what happens in the past. She confirmed R399 and promise that R399 will be debited for 24 months. Suddenly on 1st March 2025, R573 was debited, which I didn't have any agreement for it. I called and emailed. I even explained that if this happened again, I am going to reverse so that they can stick to our agreement of R399, as I was supposed to be paying R459 which I did pay in February 2025. Then R519 was debited on the 1st April 2025, without my consent or approval as the is nowhere we did agreed with both amount. I was ****med for R790 by an agent of DStv. Can you please help 🙏
