Tracker technician taking their own sweet time

The technical team is really not supportive, I had paid my tracker account on the 4th,I had to call them to reinstate my tracking device , I am told I will be given a call by them, they didn't call. They activated only one unit on the one car and not on the other car, the car which is at most risk, the polo vivo. I called them again, as the car location updates for one and not the other. I'm told there was a hardlock on the high risk vehicle and would be removed in a day, today is the day it was supposed to be removed.guess what?... It's not removed. I give them a call to simply nudge them, the consultant I spoke to is unable to get a hold of them on the phone. I just wonder to what end will this be? I mean if the tracking device is no longer in the vehicle they should notify me, if the tracking device is faulty I should know before things go messy. I am renting out the vehicle and lessor takes no initiative in making tracker payment, giving me reasons to think they eventually are gonna wanna withhold the vehicle to a location unknown to me(hence I want to ensure I am able to track my car at all times. I am currently unemployed and cannot afford to pay tracker every month and I had asked them to separate my accounts because to even have the other vehicle on contract is costing me far too much as I am becoming unable to track the leased out vehicle. I fear cause I have heard rumors that the tracker technicians are part of car *****ing syndicate, I would not want to bare witness to such.
