FBA Shipment To LBE1, Delivered a month ago, still not moved to Checked In status, No support availabe for sellers

This is our first time shipping to warehouse LBE1 , and our shipment FBA18QVK8YTH was delivered on 06/01/2025, till today not moved to checked in status, it is small package shipment, according to amazon policies small shipment takes 4-5 days to move to check in status after delivered to FBA warehouse, being a seller we do not have any option to escalate the issues, amazon support just copy and paste policy reference being a seller i feel very disappointing, no support for sellers

please help, my item have been out of stock for so long. this is the longest warehouse i have been waitting for, after LBE1 search in the seller forums, i do see so many delays like me, which makes me worry more.

FBA ID: FBA18TQDG84W

We sent over 140+ units sent to FC LBE1 and no updates in 3-4 weeks. "Checked-in" on Aug 7th and nothing since. I have seen others post on LBE1 and their shipments have literally no update whatsoever. What are we to do? I have sent 2 other boxes to other warehouses within this timeframe and those items have been received and making sales. So what gives? Do we keep waiting? Never have waited this long after delivery. I am trying to make another shipment and of course, it wants to send it to LBE1 but I refuse to make one as I don't want inventory stuck for weeks or months at this point.
