Do you mean change your feedback you left? A review is something different.
You can only change the neutral or the negative you left to a positive by asking the seller to send you a feedback revision to complete, but be sure if there had been any issues with the transaction, this has been fully resolved, and you are not just changing the feedback on ' a promise'.
Positive feedback cannot be changed, but this is not taken into account if you do need to open any case for that item.
Feedback as you have experienced, can be left in error!
