Which apps allow you to pay credit card bill via debit card without convenience fees? Checked mobikwik, freecharge and phonepe.

Gotta revive this thread. As of July 2025, which apps still don't charge extra for credit card bill payments using a debit card—preferably the RuPay ones? I currently use PhonePe, but for some reasons, once that budbak fetches the due amount from Bharat Connect servers, it doesn't bother to fetch the latest amount due the next time in case there's any change in it (For instance, if the bill is paid partially elsewhere).
