Etsy worst online business!!!

The worst online business - ****mers!!! I’m sure they write their own reviews. This is my 2nd order on Etsy - Miela Jewelry and Ida Jewelry. Pay them, get a tracking number and before you know it, your parcel has been sent back to central warehouse due to no receiver details on waybill ??? Is that even possible that you can send a parcel without completing the sender and receiver details? And Miela Jewelry said she refunded me the money, but on my side it shows / uncleared!!!
