Caryrack bulling and Harassment

I have been with cartrack from 2017. I purchased my own 2 units. When I sold the car I paid for de-installation of the device. I never saw my device again. DUring 2022 I bought a vehicle and a new device was installed. I kept on asking about my device no response. I had no problem with accounts or even technical problems. However on the 29th of 29 November 2024 I sold my car requested a de- and te- installation. The device was removed on the 29 November 2024. On the 10 December 2024 the premuim was deducted. Eventhough bo service. On the morning of the 29th December 2024 another premuim was deducted. The same day the installation of the device took place. It complaint and wanted to stop.payment as I had 2 premuims taken and no service. We agreed to deducted these 2 premuim from the installation charge. On the 10th the balance were deducted plus the extra premuims and another premuim. I then stopped the 2 premuims I sold the car and till date struggling to get this 8ssue sorted. After all the bulling and harrassment. I decide to end the contract. I have now file a complaint with the Motor Ombudsman.
