If possible, you should try to work with the seller to resolve any transaction issues before you leave negative feedback. If you do decide to leave negative feedback, make sure it's fair and factual, and relates specifically to the transaction. Sellers often respond to negative feedback and may get in touch with you to try to resolve the issue.
