Pay at Pump Problems

I’ve seen there are other posts on this, but couldn’t see a way to add to them. Out at the minute and only have phone with me. I couldn’t pay at Sainsburys auto fuel pump this morning, just kept getting declined. This was curve metal. Rather a nuisance really, paying for the privilege of not being able to pay and losing out on cash back too. Why is this Curve?
