Need information: Game Masters ignoring issue for a month. How to escalate issue?

[Jojoya]

Make certain you're not going into too much detail on your ticket as that could confuse what your actual issue is.

Something simple like "the job Soul Crystals for the unlocked Reaper and Blue Mage jobs are missing from my character and its inventory since an inventory rollback was completed on X date" would be best.

If the GM needs more information than that, you can give it to them when they talk to you in game.

Also, as someone suggested earlier do "/isearch soul" in your chat box if you haven't already. It will list all the job Soul Crystals that can be found in your character's inventory, Armory Chest, chocobo saddlebag and retainer inventory. It could be that the GM left the souls in a different part of your inventory. Look to see if Reaper and Blue Mage are listed, if so you can than click "search for item" to see where they ended up.
