Contact which company?

If you want to contact your financial institution, do note that it may potentially prevent you from using the same card on DMM website should you want to register a new account on that site.

If you want to contact DMM you'll need to be able to speak Japanese and whilst you're at it you may as well ask them why you cannot log into the account. Do not discuss with them that you're playing kancolle, otherwise you'll potentially make the situation harder for others wishing to play the game. They may be able to see which games you have played historically and what you have purchased but don't give them a reason to patch their systems.
