Amazon Retracts FBA Inventory Loss Reimbursement 5 months after???

Long story short, I had over a $1000 of inventory lost for months and months with Amazon FBA. After numerous discussions and talks with associates, sending proof of purchase, etc, they finall reimbursed me back in August. It’s now January 31st and I noticed the exact amount credited to my account has been taken out with zero communication or notice. I double checked my inventory and each item is still listed as zero. Anyone able to offer any advice?
