Recently active problems in 37signals about Basecamp

The Basecamp message syntax is terrible. Can you guys at @37signals listen to user fededback and work on it? Thanks.

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?
