Terrible service

I have been phoning Renault Princess Crossing for 2 weeks now, either no one answers or the person that answers does not know or the person is not there or I just keep getting transferred. I am being forced to drive all the way to Renault Clearwater as they answer the phone and assist - if they person isnt there then they even get the person to phone back. All I wanted to do is book in my car for a minor service and take my car to the closest Renault but there it has taken me 2 weeks and no success. I cannot believe that I am not able to make a booking at your firm.
