do transactions like in this thread when a person mistakenly paid higher fees without knowing about it will get refund from miners?
do the refund need to send any request by messaging or emailing or it have any other platform? who will give the refund the pool if the transaction was verified by that pool or when the transaction is verified by an unknown miner then how can anyone will request for a refund and where will he find that unknown miner? what if the miner denied to pay the refund? like if we lost our money then we can complaint to police, is there any authority in this type of case?
do the huge mistakenly sent transaction fee also shared between every miner of that pool?

sorry for too many questions but you explain in understandable way so i asked.
