Where's to find loan agreement?

[Fobss]

I've tried using the loan agreement ref but it says invalid credentials I always seem to have an issue every year with this apparently it's 8 characters but the one I have is native massive with multiple hypens Inbetween

On klarna it is the order ref, everything before the hyphen

I get an email notification of my next upcoming payment but if I go to the customer portal it shows me summary from a previous transaction with zero balance and there is no option to try a different agreement No so at the moment I have no idea how to check my balance? Very frustrating 😕
