Baaaaaaad service

I have never been fustrated b4 as i am now im cartrack customer three of my cars are fitted with their unit, but the treatment im getting from them does not suggest. I bought another car in december and i requested them to remove the unit from one of my car and fit it on my new car. I was charged for the fitment on the 24 december technician came after fitment he couldnt start my car he called the senior technician they both couldnt unril the night, they said they come the following day to start the vehicle the day later they both came. They tried the whole day with no success. They told me that i must get another technician to fix the car and invoice them thay will refund. I made a lot of phone calls i was taken from north to south with no success. Ultimately they deducted R599 from my account when i asked im told is a call out fee when they sent the senior technical to come and fix where as i did not call or do they fix my car. I was hesitating to go to court thinking the problem will be solved because is not that big amount.
