Car Track SA Bad Service

I bought a brand new vehicle and Car Track fitted a unit on the vehicle tafter that my dash cluster started playing up.They sent three technitions on three days but could not sort it out.The vehilcle was taken to Ford to sort out.I canceled the policy verbally with them the second day the unit was installed but they insisted to try and sort it out eventully the vehicle was refunded.The issue is now that they call me constantly asking for funds for a unit I dont have anymore or never used.When you deal with Car Track be very careful as they are very suspicious and underhanded you cant get anyone to sort your problems out and when you go to there offices in Rosebank you will see how a bad service and bad customer care can get in this country.I have a business account with them and have cancelled it today as well.
