I took my car (opel corsa 2009) for major service of 60000km on 1 Dec, after 5 days there is warning sign of ABS which makes speedometer and petrol gauge not working, i took it back to GM to fix cos surely they've done sumthing wrong or they removed other parts of my car, it was at GM from last week till today, everytym when i phone they tell me technicians are still busy they a waiting for parts that they ordered, this is inconvenience and they cant even give me courtesy car, im going to pay that car month-end but i dont have it, they dont even give me feedback of whats happening with my car, that is very poor service and im not sure whether those technician know what they are doing or have qualifications. GM service department in Standerton.I want my car in good condition cos I cant drive a car not knowing which speed im driving and whether I have petrol or not.its xmas tym i want to go wherever i want to go they must do something or will take this matter up.
