asked twice for support without solution
I had asked twice for support by e-mail, but did not receive a solution: web-based payments were recently refused by several independant vendors. N26 claims that my card should work, but did not make any effort to understand the problem (I finally made payments with my 2nd private card). On vendor side I was told it's a security issue.... as lambda customers I do not have the time to follow up with all this, and will probably have to change Card Provider if is happens again.
