I can only guess, but it sounds like the problem is that the item is still showing that it's in transit. They likely are waiting to see if you do get the package eventually. Once the tracking shows it's delivered to the wrong address, or it lists it as lost, then Eden would probably refund your shipping as well. If they refunded it now and you ended up receiving the item later, they would be out the shipping. (Let me guess, is the shipping a lot more than the order total?)

So, to get your shipping refunded, you probably have to wait until the shipping service no longer says the package is en route. Edeneve had a good suggestion. I would definitely contact the shipping company and deal with their customer service. You might find out much more information that way. I think you will receive your order eventually, but if not, I think you'll get your shipping fee refunded by Eden.
