Bad service

I'm on a 12 month contract with multichoice. Today morning they suspended my services and I called them this evening and they are saying I owe R705.00. To my surprise they debit on my bank account every month on the 15th. If my payment didn't go through on the 15th of December,why wait till the 14th of January to suspend my services? I've checked my statements bank they debit every month. You know I'm thinking of taking them to court over this. Bad service. They did this in 2020 and I had to pay R769. Of which I couldn't understand it was for what. This is really disappointing from multichoice
