Had added my Curve card to the National Lottery site a while ago but haven’t used it. Went to try and use it and transactions were declined when it went through to the security verification part with MasterCard transactions on the site no matter what bank account I used.
As soon as I switched the card to old bank card it worked so wasn’t the site. Any ideas what was up? Only time I’ve ever had an issue before was when I had tried to use pay at pump in the past
