Cartrack is a ****mer

In 2024 I bought a new car and Cartrack was informed to cancel the old car. Instead they started deducting the two cars. In the new car Cartrack went on a deal with the dealership and I then inform Cartrack to give me a new quote. Till today they never gave me a new quote but instead they continued debiting my account, until I put a block with my bank. Now I am getting annoying calls from their lawyers and when I ask them to give me a registration number of a car they are calling about they don’t have. All they have is just a make of the car and vin number they got from the dealership. I want cartrack to stop calling me as I have no business with them. My car is well covered with another company
