Fake listing

Hi,
First I appreciate all of yours help and guidance you give to all sellers.
Unfortunately, second time I have the issue with same product however this time I searched by using UPC on my seller center app and add product when I sent my inventory to Amazon and it received however I could not see my store there then I realized ASIN B005IQ2M3Y I used merge into another ASIN B002S8PT8U.
Raised issue with SS they said upload updated inventory file.
I do not know how to do so.
So frustrated again removed back all inventory.
