Still being debited off a service warranty that has been completed coupled with rude service

I took up a service plan in Aug 2023, which was cover for 3 services up until my car reached 165K kms. The first service happened in the 5 month of taking the cover, then has been happening annually from then. My car had the last covered service at 165K kms, and then cover should have been ceded, but they are still debiting my account. When called the call centre to enquire, met by a very rude consultant, who claims that I am on a contract which continues until Aug 2026., hence the debits are going off. Does not make sense to me, as what then am i paying for up until then? In addition, for the last service, I had make a copayment, which was not in the supposed contract that this would be the case, where their rate is lower than the what the dealerships charges for service
