By now i am sure that you may have figured out that there is no Cancellation policy with Mayajaal just like probably with any other theaters in India ...

You can see this in their purchase policy
5. TICKETS ONCE SOLD CANNOT BE EXCHANGED, CANCELLED OR REFUNDED

Movie tickets sold online through Mayajaal are done so on a no returns, exchange or cancellation basis. Refunds of the ticket price or the convenience charges thereof will not be issued for any reasons whatsoever. By completing your transaction by clicking on the Purchase Now button, you are accepting this policy. Please select your movie carefully and double check that the session and ticket information contained under the You have Selected heading is correct to prevent you being out of pocket.
You can probably give it to your friends or colleagues ... I don't see any other option.

I think this is one option that someone can think of. Its mutually beneficial having a cancellation policy even if it means 50% penalty on reimbursement.
