Yatra — Amount deducted but ticket not done by Yatra

Website:

www.yatra.com

I booked to and fro domestic flight ticket and the amount is deducted. However no ticket is received. There is no way to contact the customer executive and no response on e mail of [protected]@yatra.com. This is highly unprofessional that you don't even provide a customer service. Utter waste of time. How to resolve this?
