CARTRACK BAD SERVICE

I wish i can say the service was good but instead of done a good service the tech that installed my unit on my corsa strip down the complete dash as he could not find a power source after 2 days working on the vehicle he dit not put half of the *****s back afterwards i drove the vehicle notce that there is a hell of a rattle on the dash i send the vehicle to a mechanic to repair as cartrack did not come to the table to repair it .Now i try to recover the cost of my repair but it take cartrack now 2 months to resolve the matter . Will never recomend them to any one thks is the worse service i received .
