complaint against dummy articleship



I am doing my articleship from a local firm in Mumbai.At the time of joining this firm, my CA had told me that they had 40+ articles in all. On the basis of this statement, I thought that it would be a very good firm & I joined thos firm but afterwards I realised that most of the articles are dummy & the workexposure is not good which he had promised me at the time of joining.I feel that he has really cheated me. I want to raise the complaint regarding his providing dummy to the students..Can anyone tell me the procedure for raising the complaint?
