Payzapp — amount deducted from card not credited in payzapp wallet

Address:

Ernakulam, Kerala, 682025

I have done a transfer on 4 jan 2019 of rs.4000 and the amount is debited from the card and not credited in the payzapp wallet. The icici customer service officer told me that the fund is not settled by the merchant and they can't able to refund. The payzapp have to decline the transaction. I am trying to contact from that time onwards and the call is waiting, not a single officer is attending. Kindly take this complaint and do the needful.
I need the refund of amount to the card at the earliest
