FWIW, these Apple Support Community forums are peer-to-peer support forums. You are not speaking to Apple here, only other users, and we understand Apple don’t actively participate here.
You will have to at least remain in constant contact with the repair depot to keep updated on the service. Be a thorn in their side, if you will.
In addition to that, you may find help and guidance by contacting Apple Customer support directly.
Customer Support (800) MY–APPLE (800–692–7753) or on line Support.Apple.com
or call AppleCare Support at 1-800-APLCARE (800-275-2273)
