iOS 6 and Exchange Calendar Sync Issues

My company has been having several issues with iOS6 active sync and Exchange 2010 (sp2 ru4 v2).

Issues:

1. When an appointment is updated by the organizer the initial appointment does not update on the iOS device. Instead a 2nd appointment is created at the new time causing both appointments to be present.

2. When an appointment is updated by the organizer the iOS device does not reflect the updated date / time. This seems to happen more than not with recurring events.

Does anyone know if apple is aware or what the procedure would be for me to open a case with them directlty? All iOS devices are fully updated (to avoid the tansaction log bug that was happening).
