State level may be complicit, but I think county level offices turning away donations is misinformation -- The counties hit hardest by the hurricane are probably not physically capable of receiving donations due to service outages and damage to infrastructure, since County funding is handled by either a County Treasurer or a Tax Commissioner per county. If the offices that handle these transactions are out of service, there's not much that can be done monetarily.

Volunteers may be getting turned away because of the dangers of ongoing flooding, impassable roadways, mobile debris, potential mudslides, and damaged power lines. There are a lot of dangers in disaster relief that the 5000 or so professional technicians and other responders are trained to handle or avoid that most well-meaning Samaritans simply aren't equipped for.

County level agencies absolutely ARE handling things -- there are linemen up here in WNC who have been sent from all the way from City of New Bern, who have come from the east coast of the state to help with disaster relief.

If you want to lay blame on any government agency, I believe you should direct your anger onto the National Weather Service. By the time the first messages about Flash Flood watches and warnings started appearing for the Piedmont counties, the mountains were already severely flooded -- The NWS had two days in advance that they could have advised evacuation, even in the mountains, and DID NOT DO SO.
