ARs can take days to investigate. or more.
Cinn's advice is best. If you do not have perms to return items, you can contact your LL. If it were me, and my Landlord didn't give me control over my own land, I would find one that does....
There is a buyers' / renters' market right now, and not being able to return items from your land (even if rented) should be a clear signal to move.
