Authorized debits

I signed up for DSTV Explora in September 2022 for 24 months.The contract ended in October 2024 and i was still being debited. Only to find out I've been billed an additional R105 and R199 for services I knew nothing about nor did I agree or sign up for additional benefits or subscriptions. I spoke to a consultant named Nqobile who was not helpful and extremely rude to my niece who was trying to assist me with the query. I never received any communication from this company regarding any information for their services or benefits which I've been billed for and which was never been used. I was informed that they will not refund or reimburse any money that was debited .This company was debiting my account without my authority for services I did not request.
