Lack of communication

Today I had to call because no one is giving me any feedback regarding my lodged complaint about BMW East London. I don't have time to waste, my car is stuck in East London for a month now. I have a small child and we must Uber every morning that cost me R400 a day. BMW keeps on wanting more money from me and they refuse to release my car. I urgently need intervention. I can't keep on checking progress from your side guys, I'm paying you to render a service. I know I recently lodged the complaint but some sort of communication will be appreciated.
