The Amazon warehouse lost my entire shipment, and I provided various information, but they have not replied to my email for a long time，I think the warehouse wants to evade it

Approximately %40 of my inventory is lost in Amazon warehouse. I contacted multiple times with Amazon support but no response since Jan 9. I don't know what to do and where to contact. I sent all the necessary details.

I appreciate if anybody gives feedback.

Regards,

I simply explained to Amazon team that I sent 1000 units, sold about 663 and have at inventory 240 available. There are about 80 units lost. I even identified the warehouse in which the goods were lost, Amazon support pointed out to me lost units from another warehouse, ignoring what I write about, explain and give reasons. I think I sent more than 10 emails. It's a terrible experience and I just don't want to give up.
