Hi there, maybe somebody can help me? Bought a guitar on eBay (already paid). Seller hast not yet delivered due to alleged shipping problems. Agreed on a new delivery date with him but now he wants me to close my open case/requests asserting that my purchase us still protected by eBay. Is that true? eBay says that a closed case cannot be reopened again. I don't trust the seller. What should i do? Thanks for suggestions.
