POOR SERVICE AT RENAULT VANDERBIJLPARK

I took my Renault Clio to Renault Vanderbijlpark on 23 Nov, I mentioned to them that the vehicle struggled to start. They checked, did tests but did not find anything wrong. The next morning the car did not start. We replaced the battery, problem solved. So, last night we drove for the first time in the dark, and now the lights is giving problems. The dims are not working, only the brights and only when you keep on pulling on the lever for the brights. We phoned again this morning and after being put through to several people who were unable of unwilling to help, we were told that we did something to break the lights and we had to pay R900 to fix the globe that apparently blew. Funny the car did not start and lights stopped working on the day of the service. And if the globe blew, how come the brights are still working and the order is reversed. Brights now only work on dim?? Why should we pay for something that went wrong during the service, and for a car that is still under warranty?? We were also told to bring the car in at 07h30, and when my daughter told the person that she had to be at work at 07h00, and asked is she could bring the car at 07h00, she was told that they can't help her then.
