I very much doubt you'll find anyone from CTC responding to you on here. It's not an official channel of communication. I'd say you'd be better off trying to ring them and ask, but the web page suggests that this is discouraged as well.
There are a lot of people applying, and the line has to be drawn somewhere. If you're four years over, I wouldn't hold out much hope - if they make allowances for one, where do you stop?
Not trying to pour water on your fire, just being realistic
