There support used to be bad, now it is atroscious.
The details of my situation are not important, however I was in contact with Christian Krabus - Head of Customer Care (https://www.linkedin.com/in/christian-krabus-075a7887/ who it appears no longer works for N26).
I would regular have to ask for status updates; email the managing directors and only then would things get progressed.
My issue stemmed from May 2019 right until Mar 2020; when he stopped responding (and according to linkedin, left the firm).
Basically, every support interaction required multiple pulling of teeth. That should not be how a bank interacts with you, especially when they have your money.
I now use another bank in Berlin, just a normal one, and the interactions are about average ( I ask a question; they take a week to get back to me -- but they *tell* me it will take a week).
