Prepare a concise timeline of the purchase, messages, and tracking behavior, then file a dispute through https://paypal.pissedconsumer.com/review.html asking PayPal to mediate and validate carrier records. Request buyer-protection escalation if shipment proof is missing and ask for a single escalation contact and written interim status while PayPal reviews. Clear, fact-based disputes reduce back-and-forth and help the platform reach a decision faster. Please request a single confirmation and an estimated timeframe so progress is visible and you can plan while support works the case.
