Air India Express — amount not refunded

Address: Near Shivaji Chowk, Thane, Maharashtra, 421302

Hi, on 12th jan 20 i tried booking ticket through air india call center as usual, and made 50, 000 inr (Ticket cost - 214, 000 inr). Due to some technical reason i was not able to make remaining payment hence ticket was not booked. Though pnr number was generated. Now 50, 000 inr got debited from my bank account and the transaction successful.

Air india said within 48 hours it will be credited back to bank account.

But still today on 03rd feb 20 the amount has not refunded by air india.

Kindly take serious action against them.

Thanks
