What is the best option if my case seems mishandled by my lawyer?

I hired a Georgia attorney 6 years ago to handle a misdemeanor case. It was stated that after a probationary period, he would file for dismissal of charges and/or expungement of the charge. I paid up front. I have come to find out that the case still has an open citation under my name and the attorney has not returned numerous calls to his office over a period of months. What are my options? Has he fulfilled his duties as my attorney if the citation is still as it was 6 years ago? Do I have recourse for money and or disciplinary measure against him?
