Things you can do, as a lib:

You can file an e-petition with the House (if they're successful, these usually get press, and the petition has to be presented on the floor) or get some friends and repeatedly contact your MP.

Its usually pretty easy to get an MP's attention, they're pretty accessible through twitter (I don't think theyre legally allowed to block someone fron their riding) and they often don't have too many office staff. Depending on what riding you're in, you may actually get to speak to your MP and give them an earful yourself.
