Bad customer experience

Guys Cartrack is bad news. I got an accident on 22 October 2024, towards month end, I informed them that I will be canceling my subscription since I didn't have insurance and the car is not running. They told me about a 20 day notice period because I was on a month to contract with them. I said, ok I will pay for November 2024, but that would be my last payment. Now they want to blacklist me and funny enough, that car don't even have a battery but they are not saying anything about it. They don't even know where it is but they claim that they are guarding my car.
