Poor customer service

I booked the car in for programming yesterday at Williams Hunt Pretoria and was promised that it will be attended to yesterday. But yesterday the whole day nothing happened and no update was given to me. Today I called them and spoke to Natasha who said there's no job card for my car of which I did with her yesterday. After telling her I did it with her, she then refer me to Olive who told me they couldn't get it right so they're going to be busy on it again today. I saw the car is still standing in the yard where I left it in the sun meaning nothing has been done since I left it there so he changed his story and say it doesn't have a battery which I told him that it's there and he said he is not sure when will it be attended. He promised to call me earlier because he wanted to hear from the foreman but he never. Now I lost respect and trust in the person which end up spoiling the whole service experience with these people. Please help me resolve this. Kindest regards Noko
