I understand that you are unhappy with your name change request being denied, however, we will not be making changes to the current system. Name changes are not treated lightly as its a serious change to your profile. To combat this, major name changes are gated behind the upper tiers of our donor system.
As mentioned in your denial response and our PM conversation, you're welcome to create a new account with the name you desire or you can simply achieve the donor tier required for your name change.
