Missing AC

[Zheneration]

So I logged in just now only to discover that my remaining 3200 AC went missing. Is there a way to inquire about this?

EDIT: Never mind. Turned out my AC expired after a year of purchase. So grimy...

Well knowing this I'll remember to spend my AC instead of holding on to it for a year if I ever decide to buy myself some that is... I hate that when it happens though where you can't even keep the money you pay for
