I'm stuck at activation lock! (Iphone 5 factory reset)?

I had been on punishment for a good 3 months. So when i finally got my phone back I'm currently stuck on the Activate iPhone screen. They changed my info to where they could see my text and all. (Over protective parents). The thing is, they did it 3 months right when they took the phone. So when i got it back they forgot the apple id password, security questions, and the emails she used to reset the password and my account is currently disabled for how long, i don't know. And she doesn't no the current email address that could be used to verify the identity so every time i try it says, Your Identity could not be verified at this time, please try again. What can I do? Who can I take it to, and will it cost?

Activation lock is unbeatable and only Apple have the ability to reactivate a locked iPhone under strict conditions.

If your parents paid for it, still have the receipt with one of their names on it, and if the receipt has the phone seal or IMEI number or the receipt clearly ties to a delivery involve with the same information then the documentary proof of ownership is complete. The named parent can then make an appointment for the Genius Bar at an Apple Store and take along the phone, the documentary proofs of ownership and usually two forms of ID such as a recent bank statement or utility bill with the owners name and address and a passport or full driving licence. If Apple are totally satisfied as to ownership then they can then totally wipe and reset the iPhone. I don't know whether a fee is charged for the service or not, and the process does lose all data stored on the iPhone so hopefully you've been backing it up as the manufacturer recommends.

If Apple have any doubts at all about proofs of ID and ownership or if there's no link between proofs of purchase and that individual iPhone then they'll refuse to re-activate it and the phone will remain a useless handset suited only as a spare parts donor.
