Tracker is turning into a ****

Tracker is behaving like a big **** these days. Our car was in an accident. We notified the tracker and requested for the account to be cancelled through calls and emails. Around July 2023, we were told that there was an outstanding balance that we needed to settle before you could cancel. We settled this amount and sent proof on 29 September 2023. They did not cancel the account and are still billing us. They say we owe an outstanding balance incurred after we had settled an "outstanding" balance and are sending us reminders to pay. It just shows that Tracker no longer cares about their consumers now, they just want to collect money. I don't get why they refuse to cancel this account. And to show that they know what they are doing, the absolutely acknowledge everything but request to cancel.
