bad service

I took my car for service on the 10/02/2016.When I got there I was given the forms to sign with the wrong information.The car details were right but I was called by mrs Buthelezi.I was done before 8:00 but only left the dealership around 08:40.I got to work at 9:35.I never recived an sms like they normally send it.Got a call during the day,and I was told I need to replace 2 tyres,I told them it's fine I will do that on my own.I got another call just before 16:00 and he said my car will be ready by16:30/45.I got there around 16:35 and I sat for about 20 minutes then they told me they are still busy with the car they need to replcae the battery.I had to wait some more until I told him I need to fetch my child from school.He said he stays in Boksburg he'll bring the paper work by my plave sign as I needed to sign for the warranty aswell.I'm still waiting even now.I regret buying another hyundai,I can't wait to get rid of it.The service there sucks big time.I was not the only one complaining that day.Now I see why my husband decided to leave hyundai and go for another brand,I will have to do the same.Everytime you go there it's a different story,I've had enough...
