My Mastercard is not getting accepted --> i cant register

Hi!

I am really interessted in checking out Azure, but for whatever reason you guys dont like my Name or something, because both of my Mastercards are not getting accepted.

I tried both of them on other Websites, like Amazon, DigitalOcean etc, and they get accepted without any bitching.

So could maybe a Admin manually enter my Data or something? Its really frustrating, and the CARDS WORK GREAT EVERYWHERE ELSE BUT HERE.

Have a nice day!
