Faulty unit

I started my contract with cartrack in 2020, everything was fine until my car was written off. When I got another car they charged me to move the unit from the old car to the new one. After the unit was installed January 2022 in the new car it's been HELL. Everytime I lock my car I receive a call for power loss signal. I have been reporting this issue since January 2022. So if I lock the car 15 times in the day, I receive 15 calls. Every consultant that calls me says they will log a ticket for me but nothing happens.

When I call the customer care they say I need to call the fleet department. The fleet department doesn't answer calls at all. I called until I gave up. I sent emails but still no response. I am fed up, I want to cancel my contract and they charging me for that too.

I am really fed up, I just want out.
