Very poor service

Hi

I requested Car track to install a device on my car on the 3rd of July and their technician kept postponing for 5 days until I called their call center to find out if i can get another tech and I was asked to come to their Borksburg branch to get it fitted on the 8th. A few days later my car wouldn't start and my instrument cluster sometimes flickers and i have called, left countless massages on their Facebook and inbox, all i get is that they have escalated it and someone will call me. Its been over a week and i cant use my new car because of car track i have to kick start the car every where i go. This is by far the worst service i have ever received from any provider. Im actually worried if they will be able to recover my car if it takes them from the 3rd of July to the 20th to resolve 1 query for me.
