Last year MadHatter was pretty trustworthy, but then he got distracted and I suppose didn't want to deal with it anymore, so has become increasingly unresponsive. I wouldn't recommend dealing with him.
I think you are confusing this exchange with another.
Just so there is no confusion, Bitcoin2Cash LLC is a U.S. organization.

The operator only has had positive ratings in the Bitcoin OTC WoT, though no new ratings in the past couple of months.

It would seem entirely possible that the order matching component of the site is not functioning, thus any orders that would clear are not getting processed.
The forum user account does show activity in the past 24 hours, have you tried PM'g the operator?
