The last thing to do if you still haven't solved your problem is to make an appointment at the Apple Genius Bar for service. If you need to find an Apple Store - Find a Store - Apple. Also, see How to find your nearest Apple Authorized Service Provider (AASP) or Distributor (AAD).

The Thunderbolt 2 port could be used but only if you could find a Lightning to TB2 adapter. I don't know if they are out there but you can hunt at Amazon for one.
