If they have asked for identifying info and you’ve given it, and mediation is underway, there is not much more to be done on your side. Best advice if once been given was to tell them to ‘#@&$ off and shut the door’. I did that 5 years ago and tho the committee is apparently still wailing, I’ve moved on and just ignore them on the issue completely. Life is much better without their added stress and suggest you let them do all the work and ignore them too.
