Over 4 hours ago, I bought the Valentione set from the Mogstation for use in my glamour set. However, they still have not yet arrived.

I was online during the purchase, but since then I spent 3 hours offline, so I know relogging won't fix it. I also know the payment went through, because I bought it through my Steam funds. I have also deleted all the opened mails stored in my mailbox and tried using the Reward Deliver Request option numerous times. Neither of these option have worked. Additionally, I only have one character, so I could not have selected the wrong one.

Where are my items?
