Character Transfer Bug

I am trying to do a free characters transfer off of Old Blanchy (US) on Wrath Classic servers, but there seems to be a mailbox bug. I currently have no mail on ANY of my toons, and it is saying I am not able to transfer because of something in my mail. I have relogged multiple times, waited days, still the same issue. Even tried sending stuff via alts to sort of “reset it”, but nothing has worked.

If anyone has any tips, that would be greatly appreciated - Trying to open a ticket or contacting ANYONE from blizzard is about impossible these days.

Thanks,

Having same issue here. No mail but it says I need to clear my mail before transfer.
