HDFC Bank Payzapp — failed transaction

Address: 560038

I transfered 4500 rupees in for medical cause to one of my friend through payzapp but transaction failed and my amount was deducted from payzapp wallet. I wrote multiple message at [protected]@payzapp.in, but there was no one to look at our concerns. payzaap is virtual platform for money transfer which has a team of virtual people and it has started to play with the sentiments of people by blocking there money for there personal use.
