I had a personal and a business account with them for a few years now. The account was used to send a receive money, mostly making payments to bank accounts in other countries. Then two weeks ago, I suddenly received an email out of the blue, telling we that my account was canceled. My access to the account was blocked. No reasons given whatsoever.
The email says I can contact them and appeal the account closure. I did that right away - asking for clarification and return of remaining funds. So far, no answer at all.
I am luck that there was only the small amount of app. €200 left in the account, a couple of days earlier and we's be talking about €12k.
Anyway, I suggest that if you do work with them, be extremely cautious.
