What can I do about my incompetent dentist? Wrong colour veneers and chipped! (Photo)

I had my teeth whitened but as I had composite bonding on my teeth I had to wait until they were fully white to get it replaced. As an actress, I needed this doing quick so ended up paying (£139 a tooth). I explained that I had problems with my teeth as a child which meant they yellowed underneath. He got the wrong shade completely, and I had to go back as the shape was wrong and now my tooth is chipped. I had to return six times as he also kept cancelling appointments. What can I do about this?
