On every listing is eBay's 30 day MBG Money back Guarantee policy. For any item not received you Must claim within 30 days of the item's last estimated date for delivery, and if the seller does not have tracking to prove that delivery, you are guaranteed a refund.
Never continuously message a seller, they're stalling for time, so you are out of time to claim.
You open a case, if not refunded within 3 days, and no valid tracking number entered, you escalate the case, eBay step in and force the refund.
