Unsatisfactory services

My vehicle has not been reporting for 70 days, I have been calling for maintenance to replace my unit, I have been told there's no technician available for the region I am in, they keep giving me the dates for the coming three to four weeks for the technician to attend to my request, the question is, what will happen in between if my car is ******? will they cover it, or will they tell me that my unit was not responding so they cannot find my car? I have asked them the same question, no one answered. I am being debited every month for the services that I am not receiving, very disappointed with the services. even considering moving to other tracking company.
