Cartrack dont act like a ****!!!

I have a cartrack account and since Ferbruary 2020 my tracker was not working and I was not aware , and they were busy billing me until I only got a call around April , when it was covid lockdown and told me the tracker is not working so if something happen to the vihecle they will not able to see it ,since then I have been trying to get the matter fixed and they will come with excuses, the billing departemnt will call 2-5 time a day harassing me about payment yet their service was not working !! Until today they have been billing me and they just sent me a final demand letter, but the problem what I m I paying for ?...Anyone who is reading this please help me to get a better company with a better service, as I will pay this and close the account. I have paid whole year for nothing disgracefuly they dont even know where the car is . Cartrack be real
