False debits

I took out a contract in 2021 for an explora decoder which I was paying R169 for. Contract ends in 2023 August they keep debiting me saying there’s a month that I skipped but never phoned to say hey your debit order didn’t go through. Anyway they tell me they’ll debit the last one in October fair enough I let them. No debit was made in November hippie I’m done with this misleading company because they sell people lies. Come December they debit R89.00 and I’m thinking to myself what now it was the festive I just assumed no one will be there to answer my calls. Then they debit me again in January. I call them and they tell me it is a technical subscription in case there’s something wrong with the decoder then I can be able to get assistance *** no one told me about this and it was not stipulated in the contract??? I want to stay so far away from this company they’re a bunch of *****s.
