MAAC
Offered course not yet started

I want to sue Maya Academy of Advanced Cinematic. On 04/02 I purchased a deal from Internet. The deal offered me 6 days of workshop in Photo-shop. I have done all the required things including filling up the forms and submitting other details. Till date the institute have not started the course. For the purpose of being in touch, I even called the institute 3 times only to find no answers regarding my query. Please help me to teach them a lesson.
