I've been using Klarna for a good amount of time. My payment history wasn't completely perfect, but I usually had a fairly descent purchase power. Then out of nowhere my purchase power is $0. Contacted customer service several times and their response was that they are going through a system update and I'll be able to see my purchase power on the My Klarna page of the app and see my updated purchase power. Still $0, but yet they don't mind taking the payments.
