I have the free curve card. Prior to getting the physical card my test payment went through and was refunded, I also bought £50 of premium bonds. Once I received the card itself I have tried to make further NSI purchases but each time it is declined with a message refer to Curve card supplier. I have mailed customer help several times but no response. Any help appreciated
Might be worth trying a different underlying card. Otherwise need to take it up with Curve Support I’m afraid.
it could be either you don’t have cuve fronted turned on, NSI doesn’t accept credit cards or curve without it being turned off.
hope it helps
