I tried looking around on the BE site as well as the forums and was only able to find what you found in regards to who to contact and i doubt using the contact us page on the Site would be much help because you have no way of knowing who exactly it is your contacting.
to ban you from the forums for speaking your mind and some home truths i thought was going a tad to far, your conversation on the IRC sounds interesting, I use to think the staff were OK and not like most other ISP's but now i'm not so sure, they seem very keen to shut down anyone who says anything negative and truthful that points the finger at them for being at fault.
there is a contact us page on the site in which there is a complaints section whether that goes to anyone of importance that would be of help i don't know, might be worth giving them hell via that it can't be any worse.
let me know how you get on, PM if you like and if your not able to post on the BE forums again.
by the way you can probably guess who i am by the user name, it's not that far off from my BE one minus some digits
