Rovi Chew review for Walmart Marketplace

Get the products in listing was quick ease but then the product remains in publising I adon't know if its already alive. I try to find out information how long it takes but there is not information. I go the the seller center to try to see is the product is listing and nothing is published. Them I try to upload direct from the walmart seller center and it bring the prodcuto from another company I can't change the horrible pictures the others have, I can edit inventory. Is fustrating no have even a chat support to drive you to success.
