As a Biz customer, I think it's weird I can't email support

Am I alone here, or maybe I just don't know, but as a business customer, I really thought I'd have a way to email into Comcast support.  

My phone system is receiving messages from the wrong numbers,  there's apparently a PIN that i've never heard of used to manage my lines?  My answering system doesn't work.

I don't feel like sitting on hold explaining things to a 1st tier support rep.  In this day of social media, is there not a way to communicate with Comcast support in this manner?  Maybe a tweet would be faster, sure works great with other companies.
