I have participated in LD and BD, but Amazon is currently slow to list. there is a lot of FC transfer and Reserved? What should we do in this situation?

Hi all. I am now at a total loss. I have only been a seller for 4 months and use FBA for everything believing this was the safest way. however out of the 14 boxes I have sent over 4 shipments, Amazon have managed to loose 5 boxes !! They have only reimbursed for 1 box. My highest value items were in one of the boxes and of course this is not being reimbursed despite their own policy,. All of these have gone into Coventry.

Does anyone in the UK know of a route to escalate beyond the auto email replies which just state that the items are lost and the case is closed ?!!

TIA

My products at FC Transfer suddenly became unfulfillable. My products were counted as 63 pieces 4 days ago and FC transfer was started. This shows that Amazon received the products as I specified. Then, when I checked 3-4 days after the FC transfer process started, I saw that all of the products were in "unfulfillable" status today. Quite clearly, the situation is that the products were damaged during the FC transfer and became unfulfillable. At this point, we request that our loss be compensated and the issue be dealt with meticulously.

Best regards
