Dstv multichoice

I am very disappointed with Dstv. I contacted their call centre on 11/10/2022 to arrange for my package to be deactivated and my debit order to be cancelled. Which the lady promised me then was done. On 24/10/2022 I get a message that the debit order will go off on the 27th. I phoned call centre again. Another lady assisted me, she informed me that the previous lady forgot to cancel the debit order but that she did it now. Assuring me that the debit order won't go off on the 27th and that my package will then be deactivated as I have requested. On the morning of the 27th my Dstv was deactivated but low and behold! They still tried to collect R839 from my account that day. And now because I did bo5t have funds in my account (which is the reason for cancellation because of financial difficulties) FNB penalized me with R105. Which I feel Dstv should pay because I have cancelled the debit order twice with them! I even cancelled it on the Fnb app. How can this be! I want Dstv to refund the penalty fee into my bank account, because it is their fault for not cancelling the debit order after they promised me that they have done so. They can listen to their recorded phone calls on both days to confirm my allegations.
