you can try this:
1 log out
2 find the order page in your browser history
3 login from here

in the meantime you can always message your seller, if the order doesn't show up in 10 days you can make a dispute using your order id or the bitcoin address you paid to

An order we received showed up as 'anonymous' this must have been the reason then I guess!

Same thing happened to me man, just messaged the vendor to hopefully sort it. Not fun! Hoping it works out

Ahhh I've had the same yesterday, thought I'd be fished tbh

Were you logged in at the time? Common mistake. Done it myself. If so message the seller and explain. If you can check your internet history you may find the order page with transaction id.

Yes was logged in .
What mistake did I make ?
Have messaged seller
No Internet history but money has gone to seller
