StanJames - Card not accepted / BIN Number not in range

With it being the Grand National, I was tempted my the thought of having a flutter.

I tried registering my Mondo card, and the StanJames website just reports “Please contact support”.

According to their payments/security team the issue is that card’s BIN Number is not in their range? I’m not sure if this is short for “We don’t accept pre-paid cards”, although I did describe it as a pre-paid Mastercard and they didn’t explicitly state that the issue was with it being pre-paid.

That’s annoying :frowning: Normally that means they need to update their BIN tables to accept prepaid cards/the Mondo card specifically – did they seem up for doing that?
