Payzapp — trx failed but not getting refund and not able to contact customer care

Address:

Jaipur, Rajasthan, 302018

I did one account transfer using payzapp app on 23 oct but transaction failed due to some issue which i am not aware.
I tried to calling it's customer care number [protected] but not able to get connected this. I think this is a fake number there is no customer care of payzapp. They just fooling customers.
I wrote a mail too but didn't get response on that one too. I am clueless right now and not sure where or whom to contact.
That amount not credited to the bank account nor refunded to payzapp wallet.

If anyone can help me in this case that will be very helpful.
