Cartrack can’t keep track

Hi . So I have a fleet of vehicles which all has units in from Cartrack. I’ve recently experienced an extremely poor connection between myself and my Rep as well as the call center, via calls and emails. If there is no response all they will tell you is that the “signal is bad” and literally get back to you when it is convenient for them. My vehicle was meant to have a de&re done 2 months back, not once has my rep or Cartrack offices contact me regarding this issue . The service I experienced is extremely putrid. I would seriously recommend taking another route as your time and money will be wasted here.
