I don't know your contact's name, but am wondering if they left or if the address was removed 30 days prior to leaving. Most times the address no longer gets mail 30 prior to a unit returning home. But, to keep the unit's movements secure and provide as much safety as possible, the ACTUAL date may not be disclosed accurately in a public forum. So, I am wondering if your packages may have gotten in under the 30 day wire or if the unit was returned early.
As far as what will happen to the package...it is really hard to predict. I would lay odds on returned, but that is never a guarantee.
