It’s a hassle cutting ties with CARTRACK

I cancelled my contract on the 25 of November and I was informed id have to pay my contract on the 27th of December, I’ve been struggling to dispute this because I don’t understand how do I pay for a contract that I’ve cancelled with no Arreas. I’ve been getting different information from every client services agent I get in contact with, I then received a call from the client service TEAM LEADER after writing on hello Peter a week ago and she told me my contract is pre paid, I won’t be liable to pay in December because I cancelled it with all arreas paid. Car track has been trying to debit my account since the 13th of December (my debit date is the 27th). When I ask what this is about they telling me I’m liable to pay December installment for January Cover. I’ve been asking for the recording where I spoke to the team leader and they refusing to provide me with the recording. Can I also have my policy documents. I want to escalate this to the OMBUDSMAN
