I read on a seller forum that you can’t do anything or rather Amazon won’t look into the missing items until 45-60 days have past since the last ledger event, in my case the shipments have closed and show 0 items received. Trying to decide how long to wait, though when this has happened before to a lesser extent( 3/35 items missing on shipment contents page) the items still have not shown up after 3 months.
