I received an Indefinite Restriction on my Ebay account after 16 years of selling with 100% feedback. eBay told me I was selling counterfeit items (which I was NOT). I had an attorney trace the origins of the items and they found them to be 100% legitimate. After my account was restricted buyers began to open disputes because they got messages my listings and selling privileges were removed which made the suspicious. Ebay immediately closed the disputes and refunded the buyers without consulting me. These buyers received a full refund without ever returning the item or any messages from me. My paypal account balance is close to NEGATIVE $1000. I contacted Ebay several times to speak to managers which never rarely called me back. They told me there was nothing that they could do and that the seller has NO protection in this instance.
