WotLK Lost item

[Larvax]

Hello!! About 1 hour ago I bought the item "Rumbling Rampage Faceplate" for 75 Emblems of Triumph from the vendor in Dalaran and only lost the emblems because I didn't trade the item, it didn't arrive in my inventory and I checked it out. The mail and the article did not arrive there either, I wanted to know if there is any solution for this, that the article or the emblems can be returned at least to try to buy it again.
Thanks in advance.

Disable your addons and see if it shows somewhere.

Also, when you buy something from a vendor you get it in your inventory immediately; there's no mail.
