Payzapp — refund not processed

Address:	184102
Website:	Payzapp

I have purchase a product from jabong worth 2969.11Rs using payzapp and returned the product and jabong has refunded my amount on 1st Jan but I have not received my refund as payzapp is not processing the refund. I have called payzapp customer care number around 20 times but they don't pick the call even after waiting for 15 min. I have talked to jabong also. They also fail to help me as they told that the refund has successfully processed from our end. They have share a bank reference number with me. They ask me to visit my bank branch too and I have visited twice but my bank said they dnt have detail of such transaction.
