OnAir poor communication and a ****

I had a 24 -month contract with OnAir TV from 24/01/2023 paying an amount of R199.00 per month. The contract ended this year 2025 but they are still debiting me an amount of R105 of which I don't know what it is for. I have tried to contact their number to enquire about this debit with no luck, even sent emails with no response. I am agitated by this and needs to stop immediately because this R105 we never agreed for and it's a ****. Please assist to put a stop to this.
