I returned to retail from classic about 3 months ago in preperation for TWW, and noticed a few character missing from my character list, now called a warbond (warband?). I thought maybe in the deleted character list, but that was unavailable due to some issues they were having, and the feature disabled. That was fixed last week but these 5 characters are not there also. I contacted support, they “looked” for them but have no record of me having characters by those names in their system. Said one GM, “it seems you characters have been purged and deleted from our database.”
I responded, stating that this is less than good news, given 2 of the characters are my oldest created, from 2005, and two have had paid features associated with them, faction and races changes (able to show this easily enough in my account transaction history) so I asked if they were able to provide something for this error. A free paid service, like a character boost or something. Somewhat meaningless, but just something for having lost something like that.
Nothing can be done, I know I just wanted to vent post. Just keep it in the back of your mind. They can just lose your characters because of whatever reason, and just say they are sorry.
