Dear grand_deal
From your post it seems that you have filed the FVF Credits and the same are not reflecting in your account.
I suggest you send the Item ID's for which you have filed the FVF credits and the same are not being reflected in your account.
The customer service can investigate if you provide them with the item ids, please contact them
