REMOVE MY INVENTORY

Since my account has been deactivated, I need to remove all my inventory. Most of the inventory I have already removed by creating removal order, but there are still hundreds of products that I can't remove. When I create a removal order, some of the inventory can be created for removal, but then it gets canceled by Amazon, like in image 1. Most of the inventory can't even create a removal order, like in image 2.

Does anyone know what I have to do to remove all the inventory?
