If it's possible I would hope that they will be re-listed and move the deadline so I and everyone else who has same problem, would get certain amount of money from their players.
It really isn't possible. Connection problems are a reality in any internet service. When there is planned downtime or a bigger problem is detected in time, the deadlines of all players can be postponed.
If you want a certain minimum price for your player, never list them for less. Obviously that will not guarantee a sale nor will it help with the case you had with your player 2.
