Amazon FBA lost a parcel and then found it

Amazon FBA lost a parcel with 15 items in stock and then found it. I sent 15 items to Amazon that were popular and it turned out that Amazon lost them, so I got compensation. Now Amazon has found them and there is a period where these items are no longer as popular for sale as they were. Luckily, when Amazon lost them, I ordered another one from the manufacturer and now I have 15 pieces in Amazon and another one in my warehouse. Is there any Amazon support here that could check this whole situation?
