you can try your luck by paying with cred.
I tried multiple times with mobikwik (since it has 1% back upto 100 on full due payment), but for some reason it can't process pnb card payments. tried atleast 7-8 times in the last 3 months, failed every time. my other cards are working just fine.
if there are any other apps, pls tell. I'd like to know.
