Cred — Refund issue (cred)

Address:	E-199 Gali No-3 West Vinod Nagar
Website:	Cred App

On the 05th sep i made a payment of 14122 and same was debited from my account. i received a message stating there was an error and if the amount is debited same will be credited to my account in 5 to 7 working days. i drop a mail and request to refund the amount in 24 to 48 hours as this was a credit card bill payment but they did not responded.
Till date that is 14th Sep i have not received my refund. i have raised complain to cred grievance, HDFC Bank where i communicating with them under Ticket ID – DELC[protected]
But they still not return my amount..neither i received from cred side nor on Bank side..what should i do.
