i Have a shipment ID :FBA18X6FFGBL. it was in transit from ontario to calgary. the carrier had a delivery appointment set which they missed due to logistics. when they tried to book another appointment they were not able to and when i checked it looks like amazon cancelled the shipment because we didnt cancel it.

i've tried communicating with seller support to no avail as this was there response (case ID 17863762471)

"Thank you, for bringing this problem to our attention. I have reviewed your issue regarding shipment status change for FBA18X6FFGBL in detail.

After a review of your shipment [FBA18X6FFGBL], we've determined that we will not be able to change the status as the shipment is [CANCELED].

If your shipment was canceled, but you still plan to send in your inventory, please create a new shipment and apply new FBA box IDs that correspond to the new shipment.

If your shipment is in transit to our fulfillment center, ask your carrier to confirm that they have a valid and active delivery appointment in "Carrier Central":

https://carriercentral.amazon.com

Once the appointment is confirmed, the fulfillment center will receive the shipment as planned.

Note: Shipments that are [CANCELLED] cannot be reopened and will not be expected for arrival at the fulfillment center."

however The shipment is already in transit and has been for the last week. The carrier is unable to create an appointment because the shipment has been cancelled. We didnt cancel the shipment on our end, it was cancelled by Amazon.

We are unable to make a new shipment and apply new labels since the shipment is already in transit.

what can we do?
