Navigating lost items and/or unshipped items on Buyee

So i have been using Buyee for over a year now, tons of amazing purchases and always been happy with them. Ive probably won 50-75 auctions and done a lot of package consolidation and what not, never an issue, BUT 2 weeks ago i won an auction and it was shipped from the seller to buyee and seems to be lost, usually things arrive in under 5 business days within japan, and it has now been a little over 10 business days since being marked as shipped from the seller, yet to arrive at buyee.
I also had an auction i won that hasnt been marked as shipped and its been almost 10 business days, i looked into the seller and they have been gaining more and more negative reviews since i won this auction. Unfortunate in both cases and im wondering if anyone knows the way this will likely play out for me?

Bad things usually happen in 3’s too so i wonder whats next
Sorry if there is already a thread for this, i couldnt find one.
