FBS Postage purchased through seller central, non payment error

I am hoping someone can help me, I have reached out to amazon and so far they have been no help. I have been selling since 2020, purchasing all shipping labels through seller central. Since Tuesday all of the labels I have purchased have an error stating awaiting payment even though amazon charged me for all of the postage totaling $465. I have called usps and they are not sure where the packages are but they have not been processed. Has this happened to anyone? I know all of those packages will be late shutting down my account due to late shipment. I am truly worried. Sales are already down 46% this year, this was the last thing I needed.
