Hi @yoy_99 If the feedback was negative or neutral, send the seller a message through eBay asking them to send you a feedback revision request. You can only change from negative/neutral to positive, so if you left the wrong seller a positive, you won't be able to change that.
You can also leave a follow-up comment to your feedback:
