I have played since 2.0 and I never once let my sub drop until literally the end of September, and I also did not receive the mount despite being eligible within the time frame. But because I let my sub drop on the 27th of September, somehow I ended up not being eligible, which I thought was strange because my husband got his at the beginning September when the mount first began being rolled out to players.
We both had the same amount of sub time, we both played since 2.0... yet only one of us got the mount?

This promotion was super confusing at best, and I think it should atleast be extended further since it appears for many players other promotions got in the way.
