car not services as agreed

On the 4th of November (last week) I took my car to vw Newcastle to be service as it had a problem with the sunroof, mind you it has been to the service a week before the sunroof problem started, till today no one has called to tell me the feed back on the status of the car, I called the manager yesterday to ask about the car and he promised to call me first thing today in the morning and to my surprise he has never get back to me, and it makes me angry as this is like they are doing me a favour or its a freebie, I am paying for this yet the service is pathetic, they must at least tell us if they want us to go to other VW branches than doing like this.... can I get feedback on my car please ASAP....
