I'm not happy with the procedure they did, it turned my life upside down, can not recommend them

I went to the doctor to clean and fill in the holes in my tooth in November 2024, first problem that I encountered was the colour of my front tooth that that they filled, it was brown I told them that I'm not happy with the colour of my tooth, they tried to fix it as a result my tooth was left with two colours, Secondly the teeth that had holes were filled but the pain is unbearable, I really don't know what he did with my teeth, I'm now drinking painkillers everyday because there's so much pain, I can't even drink tap water because there will be too much pain let alone biting or chewing something I'm only relying on one side of my teeth to eat.
