Customer services sucks - totally unresponsive

I've paid for the top-level $149/month plan which includes Campfire, however, it continues to block us from using unlimited chats and list ads within the conversation. This has been a problem for months now. After several attempts to contact customer support, we still haven't heard anything back. Ugh. Anyone here have connections to 37signals customer support?
 
sad I’m frustrated
