What's app payment is not working good. Payment to request from merchandise always gets failed. When I called to customer care, response was not satisfactorily at all. Just asked me to follow help section. As if person on call didn't know anything. First thought, it was error from bank side, but when I linked that account to other UPI app, no problem at all. Recommend what's up authorities not to get in payment system. Just be massgener app.
