Nostalrius Begins - Quality wow vanilla realm (1.12)

Level 8 Dwarf Rogue training Leatherworking in Ironforge from Fimble. I was trying to learn the pattern for Light Leather Bracers (level 70 LW). I clicked to train them but didn't learn the pattern, and lost the cost of the training. This happened twice. Not sure what to do... Don't want to have to go to another trainer.

Thank you,

Got a similar issue with that npc, tried to learn leatherworking but he just took my money and lold at me, cant find the profession in my spellbook, my profession list tells me i havent learned it, but this Fimble guy keep telling me ive learned it!
Gettin pissed here..

The issue just happened again, but this time for the Rogue trainer in Razor Hill, Durotar. So, here I am, out of money and out of skills. Is there a way to report this? Kinda lost here.
