Poshmark / Jennie's Closet @ wardroberevamper (Poshmark Seller) Lack of Action to one of their Seller's selling someone else's merchandise MenloPark California

Store's name is Jennie's Closet @ wardroberevamper.  Seller sells merchandise on an Application site called Poshmark.

Seller does not return calls and emails.  Seller has sold 30+ pieces of product that I owned Month to Date.  The Seller is in possession of another 100+ pieces of my merchandise.

i contacted Poshmark regarding the unethical business practices of one of their representatives.  I was told that they can't do anything based upon just allegations.

i then forwarded date stamped emails with group pictures of my product 2 or 3 days prior to being listed on Poshmark.  You match my pictures with the listings pictures and you can see it's the same merchandise.  A 2 year old can figure it out.

Even after supplying the "burden of proof" of ownersip prior to be listed on Poshmark, I was then informed by Olivia that a police report would have to be filed before the proceed.

Clearly the path of least resistence is being taken here.  this is the internet, not a big box / brick and mortar operation.  As the Administrator of their own site, Poshmark is turning their head by allowing one of their sellers to solicite product which is not owned by the listing seller.
