I paid him about 30.000 cash for my teeth which he has destroyed I'm asking for my files to take him to courts but he has blocked me and not allowing me to go into his office

Please advise me how to get my files from this so called dentist he has destroyed my teeth never go to this person he will give you heavy drugs and do experiments with your teeth Dr Peter should not be licensed im writing to worn others and so his license should be taken away from him.
