Thereare proper ways to do retuns and you don't say whether you followed them or just made up your own way.
Did you open a case? Return (change of mind) or Not as described? Did seller provide a return label.
If done properly and seller does not refund, you don't waste your time sending messages you escalate the case to ebay to take over.
If you didn't open a case then do it now. Too late to make seller pay the return postage, but enter tracking and then escalate to ebay after 3 days.
Did you read the Money Back Guarantee as if used correctly sellers cannot stall for time and get you out of time to do things properly. The MBG is on every listing for you to read.
