Bad service at kia motors roodepoort

Today I took my car to the service, obviously the inspection has to be checked in and out Therefore when I come fetch my car the top right roof was damaged and my car was nice clean non damaged. So immediately when I have to check my car before I live,there's was this head seat that was moved very up as not ussuall.Then when I was trying to take back my head seat into its normal condition, I was surprised that the way I found my head seat was ,it seems as the damage was hidden for not seeing it until some days so that when I come complaining I must be cold different story.So I called my assistant lady who did the inspection when drop off the car to come and see what had happened.She was amazed and called the manager. I still don't believe the way the branch manager behaved to me. He told me his not responsible for the damaged of the roof of my car,and he insisted that I came with the damaged from home. I then said I cannot go with this kind of a problem back home as it was not the way it was . I gave the key back and said I need my car to be fixed.The manager then said to me he will push my car outside the yard and will be ****** if I live the key.Then I said it's ok I then put the key on the table and go. According g to this , their customer services that was provided to me was under minded very bad and embarrassed. So please please I need your your help on this matter .
