If you wish to change one of those negatives you have left for sellers, and the matter has been resolved then, contact them to send you a feedback revision to complete. It will also give you the chance to amend any low star ratings you may have left.
Positive feedback cannot be changed.
Feedback should be a last resort and not a message board, you history of feedback left for others is rather on the negative side to say the least!
Ask the seller or sellers to send you a feedback revision request.
