This has absolutely nothing to do with what SOE is responsible for and what your rights are. This just has something to do with probably the worst part of the game - CS. CS ist very inconsistent and at best looks at you as a part time cheater that tries to sneak in his mythical (or any other benefit for that matter).
I don't know if that is ever going to change but the customer service culture at SOE has many many restrictions for the actual CSR to provide any help at all even though that you occasionally hear about the lucky soul that had success with their petition. And of course you hear about the cases where customers cheated their way to updates. Logic therefore dictates to deny any customer petition of course^^.
Good luck next time with your mythical update they are getting easier each and every time.
