[Resolved]  HDFC Bank — payzapp amount deducted but not credited to bank account

I have transferred an amount of rs. 5, 000/- on october 23, 2017 from my payzapp account to my friend's hdfc bank a/c no. [protected], but the transaction has failed and it has not been credited back to payzapp account also. I am calling customer care since last 7 days, but all the time the lines are busy and i am unable to speak to them.

Kindly do the needful and arrange for the return of my amount.
