Air India — money deducted but ticket not booked

Address:	New Delhi, Delhi
Website:	www.airindia.in

I was booking a flight on 22 nov for 23rd from delhi to indore. I paid to air india which was successful from paytm but it showed error msg on air india website and ticket was not booked. I spoke to air india they told to send screen shot to [protected]@airindia.in, which i did same day but i've not received the refund for same. I tried to call air india several times but they didn't respond up to the mark
