Seems they are still having issues - Support does not respond to e-mail and they have now blocked people from chat that were trying to resolve all the issues you've mentioned here.  Personally, I pulled my miners from their pool when they weren't paying out what they promised and just left a few bucks there to re-invest, but, even that wasn't paying out according to their own calculations.

Too bad, this service had real potential, but, IMHO, if you're unwilling to address problems head-on and own it - you just can't be trusted with other people's money.
