I think you have to go "the other route" if you know what I mean. The "Geniuses" will tell you the same over and over again, you need to get in touch with someone else at Apple, like a relations rep, that will listen to you as a customer. I know it's sad that the "Geniuses" doesn't know anything about this issue and that they are basically ignoring you as a customer. I got great service from emailing Tim Cook, even though he didn't answer me personally, but I still got in touch with the right person at Apple. If you're not getting any answer there, try to call Apple Care and to talk to someone higher a Level 2 rep. If he insist to take it in for repairing a 5th time, or 12th time or whatever, let them know that you have to talk to someone else and that its not acceptable from your side. And don't hang up until you get what you want from them.
Maybe you should try that?
