Can anyone put me in direct contact with the people who run the Exeter Cavern, as in, you know them and can talk to them on my behalf?

My band 4 or 5 Magicians want to play there in August but I've sent two emails in the past and received no reply. I reckon they are getting swallowed up in the sea of crap email they must get, I can't imagine they wouldn't want to put us on if they actually read my email and listened to us. Maybe I'm wrong. Would be great if someone could put me in touch with them though!
