I ordered a ps5 controller from bossdeals on eBay. It was never delivered to me. However it was tracked by Royal mail and the email I received from them said it had been delivered and was signed "covid 19". I have told the seller and eBay I never received it. They need proof from Royal mail it wasn't delivered to me but they're saying it was. Tried the PayPal route of getting a refund but they don't believe me either. Do I give up or is there anything else I can do?
