Why does Samsung have a upgrade program if it doesn't allow you to upgrade every year to another phone, its the most pointless thing going you phone them and they are still no help, i have had the same problem every year was going to update to fold 4 but i can't cus of the broken upgrade program.
I go through the email link they provide. Been on thr upgrade program for some time now and it always seems to go OK. Only thing I sometimes get is the finance company Klarna plays up with payment options. But usually get round that. If your upgrading from the Z Fold 3 to the Z Fold 4, it shouldn't be an issue really.
Sometimes clearing your browser cache can help. Maybe also try a different Internet browser. I've had to do those at times. Maming sure the delivery and billing address are the same, as some have found that if those are different. They cannot get the purchase to work
Ye i try that as well i just tried going through the email link got the klarna part and the same thing happened it says this Your application was declined, i will try a different browser to see if that work, but thanks for your help
