Help Needed with Amazon FBA

My name is Hamid, and I created my Amazon Seller account a few months ago. I have a Belgian VAT number, and my account is in order. I want to list my product on my Seller account, but currently, Amazon has no warehouses in Belgium. Therefore, my product needs to be sent to France for FBA, and I only sell on the Belgian market, not in France. I have tried enough, including asking for help from Seller Central, but I have not succeeded.

I am looking for someone with experience in Amazon sales, especially regarding FBA. I would like to know your rates and availability. I look forward to hearing from you and hopefully working together.

Best regards,
Sarwari Hamid.
