Bad service

I took my car for its 150000 service at hyundai in bedfordview. I asked them to take a look at my temperature gauge as it keeps heating and cooling which is worrying and not normal. The service consultant also asked if they could lots of extras etc. At 14:00 my service consultant told me that my car is finished and will go for a wash they will let me know when it is complete. I never received a call again and at 17:00 I decided to go collect my car. When I got there I had to sit and wait for an hour before being helped only to discover that they only did a basic service of my car and did not look at anything I asked them to. The dealership never informed me that they did not get time in fact Jaco called me and said the service was complete. This is completely unacceptable. Now I have to book my car in again and pay the full labour charges etc I cant drive my car as I am not sure what the problem is and dont want to damage the car. There is no proper communication or service.
