I just received a notification from Ebay that I am being billed for a refund to a buyer on my monthly account. The buyer never contacted me in any way, nor did they file a "not received" or "SNAD" complaint with Ebay--they filed under the Ebay "money back guarantee". Apparently, this is a "back door" to extract refunds from sellers--beware. Of course, I am going to contest this, since I have confirmation of tracking/delivery and never had any documented dispute or claim filed against me from the buyer--no prior communication at all after the purchase. This is total BS. Just another way for Ebay and the scammers to screw sellers.
