Are those fintech companies under any financial regulatory authority? If my bank pulls any kind of stuff like that, dropping the magic "I will have to report this to the Federal Financial Supervisory Authority" gets any and all gears unstuck right quick. Because this is absolutely unacceptable, and my local financial regulator agrees (and levies substantial fines accordingly). Might be an EU thing, though.
