My cartracking device has not been working for 2 years and i need my refund 50% of my installments.

Service provider do not want to take accountability and i am sitting with a tracking device that has not been working for 2 years while i was paying my installments.

In April or early May 2023, i downloaded the Cartrack App since my cellphone didnt have enough space for apps previously, upon installin the App on my phone i discovered that one my vehicles device has not been working for 2 years, when i spoke to their team leaders they started reminding me that its my job to let them know that they must test my vehicle devices monthly and it's on the Ts & Cs.

My question is if it is my responsibility to monitor my vehicle why am i paying the provider if they can't even see if the device is working or not which means they won't find my vehicles upon theft and hijacking. I am driving a VW and it is a high-risk vehicle they keep on telling me that they are investigating the matter it's been almost two weeks and my vehicle can be ****** anytime.

Right now, i need Cartrack to refund my 50% of the total amount i was paying for those 2 years because they are not worried about my asset at all. I have to be the one calling weekly which shows no interest from their side.

After i reported the vehicle cartrack calls me weekly saying they want to test my device, it's too late now i want my refund.
