In certain circumstances, members can lose Feedback privileges. For example, a seller might file a Resolution Center case with a buyer who doesn’t pay for an item. If the buyer doesn’t respond to the case before the deadline and receives an unpaid item strike, any negative or neutral Feedback left by that buyer is removed.
As a buyer, always respond quickly to cases opened by sellers. If you resolve the situation with the seller (for example, by making a payment by phone or email), send that message through the case in the Resolution Center. Otherwise, you might lose your Feedback privileges for that transaction. For more on responding to cases, see "Responding to a case against you" in Resolving transaction problems in the Resolution Center.
Note: If the buyer is no longer a registered user of eBay when the seller opens a case for an unpaid item, the buyer’s negative or neutral Feedback is removed immediately.
