If you truly have got a feedback in a wrong manner then show valid and enough evidence to those who have left you the feedback and I'm sure their flexible enough and will correct the feedback (assuming the evidence really proves your right) but in case your just going to give nonsense proof with a hope of making the feed backs disappear then don't bother because the situation will get only worst. Just PM them with everything you have as a proof.
Thank you, i will do just that now and i hope i can get response from them because most of them just block your pm and you are not giving the opportunity to explain yourself.
