WORST CAR SERVICE

i took my car for a service yesterday and the Boksburg branch. when i got to my car the back door was still open? the driver seat still has the plastic cover on the had put on in the morning which i assume is to protect the seat. so clearly my car wasn't washed and when i opened my passenger door this morning i saw there is marks on the passenger seat????? my car is suppose to go for a service but apparently Hyundai decides they can damage the car so that the car should go for more than just a service???????? i also asked that the buckle where the driver safety-belt goes in does not work properly , they said they gave it oil but it is exactly the same as the way i gave it in yesterday morning.

this is really pathetic!!!!!!! now i have to waste another day for my car to go in so that they can fix what theY were suppose to fix yesterday!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
