HDFC BILLPAY is shit. I paid my ICICI card bill on this. They payment was debited from my account. When I received next statement, it had penalty of rs.5893 + gst. I checked with them, The payment was showing pending even after more than 40 days. On contacting them, they said that the same had failed and they offered me a compensation of Rs.200😂😂. And they never informed me that this payment failed.
