i did request a mediator, And i simply did not get one !

the seller ended up trading with someone else, thats fine !

my mediator request is now out of date and i have no idea how to cancel it now !

A med cancel option or button should be a added feature !

poll will be attached !

I do not see the need for this honestly.

When the mediator send you the pm, kindly state that you no longer require their help.

This.

You will always receive a PM by any available mediator after you have requested a mediator.
Just reply to his or her PM that you are no longer in need of a mediator, and that he or she can cancel the mediator request.
