Well there was probably a reason but they weren't told it and with N26 being online-only had noone to turn to, you can do a google/twitter search for someone getting police called on them for showing up at their Berlin HQ/Backoffice trying to get some answers.

To be fair, that is nothing unique to N26.

In fact in austria easybank is also a bank that afaik only exists "online" and easybank is much older than n26.

To be even fairer, this isn't even unique to online banks - regular banks in the US can "fire" customers without a reason and even if only because their heuristics find their profitability to be too low, but at least they get a notice and a chance to move their money.
