I'm having the same issues as last year (and the previous year) whereby I enter my bank details, and I'm told I can't use Klarna.
I have an excellent credit score, with no late payments. This seems to happen every single year since I've signed up to the upgrade programme.
What is the point in having it if every year it's a fight to upgrade your phone...it shouldn't be this difficult.
I end up waiting for tips and workarounds in order to upgrade. Is anybody else having similar issues?
