Keith said you need to send your concerns to the Bristol MP too. And then send letters and your concerns to every major politicians. I did that when I'm waiting for a long time for my visa and got a response from all of them. Send letters to Theresa May, Ed Miliband & The Labour Party, David Cameron & Conservative Party, Nick Clegg & Liberal Democrat Party. Contact plenty of newspapers. Trust me, every little will help to your agony here. They need to know about what happened.
