Junk

Why do you tell me now that my device in the car is out of warrantee and you want to charge me R600 for a technician to come and see what the problem is.. I've been a loyal customer and this is the way you treating me. I asked them to test and you tell me you cant see my car - whos problem is it that you install junk in my car that's not working? every month you charge me for something that is not working!!!!!!!!!!!
