DCed while claiming holiday mythic?

As the title states, I disconnected while tapping claim on the mailed mythic, and then my wifi chose that moment to crap out. Now when I log in there’s no mail or anything for my to check. No boosters, no nothing. I tried reinstalling, same thing. Is there a way for me to access past mail or something? I don’t want to lose out on my 2nd ever mythic because of this D:

Look at your cards. If you don’t have “Last Minute Chopping”, a black and blue support, write a ticket to the support.

EDIT: that’s the card I got… maybe there are others you can get
