3 possibilities.

A. There is some sort of event in japan or something for which the support team isn't available today and there was just the automated message but the catfood will be sent tomorrow (yeah, a bit far fetched)

B. You will never get it, ever.

C. the catfood is in your mailbox (title screen, bottom right corner) and you haven't checked.
