I was told to create a new ticket here, by Support Center Rep in-order to have a record of me trying everything possible.
I have not been able to collect my Destrier Beret from the Festive Moogle, it has been about 48hrs since I purchased FFXI Ult Abyssea edition from STEAM. Everytime I've passed by the Festive Moogle I would click him to make sure I couldn't get it.
I purchased this game again solely on the basis of this extra item.
