I was able to change it earlier but now I am not able to do it. I previously changed my IBAN and was able to see / navigate to the subscription change page but suddenly now I am not able to do both.
I am the contract holder! I took out the subscription myself.
Also someone from customer service converted my subscription by hand (to NS flex) manually in APRIL.
Also my friends took the same plan with me but they are able to modify and do the changes but not me.
Please suggest a solution for this.

I have not received a reply. I think the issue has been resolved, but unfortunately I can't be sure.
