Hi all I’m locked in Request Closed

I’ve purchased an item, it was delayed in “simple delivery” with Envi. I made a request and eBay cased it and finally it was progressed to delivery to my click and collect place but on the day it was due the item had been sent back to seller. Which eBay rejoiced in “request closed” I’m now locked in with no item and no money?
Any hints or ideas? please
