Cartrack charged me for two years for defective device, and they still charging me knowing its not working.

I had Cartrack install a tracking device in my vehicle, a SUZUKI BALENO January 2022. I have since been debited a monthly premium of R180-00. I recently accessed the Cartrack APP (April 2024) and found out that the installed tracking device has not been functioning. I called Cartrack and was informed by one of the call centre agents that the device had not been functioning since December 2022. Should this not have been flagged by Cartrack immediately and a message sent to me? Does this not immediately render me and my vehicle at high risk? I was also informed by the agent that my device would be replaced and that I would be reimbursed with my full instalments from December 2022 up until the device has been replaced. I am still waiting for a call back, I have tried contacting again many times since April. My account is still being debited even after me informing Cartrack of the defective tracking device. 5 months have gone by and nobody from Cartrack has called me to resolve this. I am absolutely appalled by the lack of concern shown by Cartrack. My vehicle and I have been at risk since December 2022 and no sense of urgency has been shown to renew the defective device.

I dealt with: *** from the accounts department.
