Consumer Redressal

Dear sir, I have given woodwork contract to a interior for 2 flats, and decided to put good quality greenply Plywood, Most of the ply he put is some low quality ply, and also he charged some hidden charges to me, then I told him to stop the balance work in other house, after this he took the keys of my house and not giving me and demanding unnecessary money for it. Please help to get rid of this situation. He is placed in munnekolalu, his name is Suresh and his shop name is style décor. Please help. Thanks and Regards Sandeep Kumar
