My front teeth cracked after dental bonding, now my teeth are sensitive and sore. What should I do?

I had bonding on my 4 front teeth for cosmetic reson,mostly at edges to close the gaps. They chipped in less than a week. I went back 8 days later to get them fixed,they end up so thin and sharp plus he drilled my teeth without using water so I felt heat and so much pain. I had to stop him twice, I was leaving the country that night, now a month later there are deep painful craks on them.he did not check my bite either. my teeth are so sensitive and soar.please help!!
