THEY SELL YOU EXPENSIVE TRACKING UNIT AND INSTALL CHEAP ONE

I'm not happy with their service, I am paying for the better unit but it always has no signal, they have to first request signal for it, on the app its showing me 3 days ago's report as Im typing this it didn't update since 21st , I did report it but the guy named Letlhogonolo said he will investigate what is going on with my tracking unit but till now, no call from him and this unit is still doing the same, THEY SUCK CANT WAIT FOR MY CONTRACT TO GET FINISHED.
