Except the situation is beyond either Sony's or SE's control. SE can't change anything about the Sony accounts, and Sony can't do anything about SE's registration of game codes. And neither company knows all the rules and ins and outs of policy as the other. You act like they're doing it intentionally to give her the run around when that's clearly not the case.

Not all mistakes can be fixed, but it's preposterous to come in here complaining that they aren't taking responsibility for her user error.
