Incorrect braces treatment and filling

The doctors in the clinic are not equiped to handle patients. Cost was low but the quality is worst. For my ortho treatment, one of the braces was broken. The doctor never bothered to fix it and the treatment was continued. now in one side of my teeth is tilted. This happened twice and the doctor at the end of the treatment asked me where is that brace lost. Such irresponsible attitude. Even my front teet are not straight. Please dont go this clinic for gods sake.
