Threatening to use negative feedback toward sellers for not providing services that aren’t part of the original product listing is strictly prohibited. Such as:
• Goods or services that weren't included in the original item's description or purchase price.
• A return, refund, or replacement of an item.
• Other improper interests
If there is a problem with a transaction, you can use the Buyer Protection to protect yourself, and work with the seller to resolve the issue.
Make sure you follow these guidelines. If you don't, your Feedback may be removed, and you may be subject to a range of other actions, including restrictions of your buying privileges and suspension or termination of your account.
