You not getting refund on crowns. It's highly unlikely. But if you want to pursue this just submit a CS ticket and just wait for a response. Ask to get a hold of Management. Management will contact you. Or you can call up Zos headquarters...Look it up online...And ask the receptionist to transfer you to ESO customer support. She will transfer you but it will be to answering machine where you will leave a message and customer support (not management) will give you a ring back.
This is what I did with a completely different matter and was able to TALK (not email) to customer service and eventually management to get my matter resolved.
You got crowns on sell. I would just shrug it off and move on. Heck you might come back to game sometime in future and you will have crowns to spend.
