bad service

hi i have been phoning car track since yesterday i have spoken to 4 different people already and no1 can assist me. i had a unit installed yesterday but the gps cannot pick up my location - i asked Lorentia from Rosebank to find out who the technician was that came out she asked me "how must i do that" very rude person, last person i spoke to was MPHO who was very helpful and told me a callout was logged on the system - had i not phoned in i wouldnt not have known - my question is when is car track going to return my calls or emails - very disappointing
