To Zoea85: Don't you think it's a little unfair to suggest the admissions tutors at Bristol are up their own arses, simply because *you* got rejected? I think there were about 1000 applicants this year for around 100 places, and most of those will have met the entry requirements. Some people are going to have to be disappointed, there's no two ways about it.
Also (I seem to say this a lot on TSR), Bristol admin teams (ESPECIALLY the Psychology tutors) couldn't care less what school you went to - they base their decisions on merit alone. To start complaining about the system in that way because you were unlucky is a bit of a kick in the teeth to those of us who are here already.
To the OP: I don't mean to sound sarcastic (it's not easy to come across otherwise via the net), but, honestly, how do you expect the phone/email conversation to go with the admissions tutors? They've had as much information as they could possibly use via your UCAS statement; realistically, you're not going to do yourself any good by getting your hopes up and wasting time by trying to make them change their mind via phone/email.
I'm really sorry; I know it's not a happy position to be in. As I said above, the Psychology degree at Bristol is hugely popular this year, which means that some people - regardless of how good they are - are just going to be unlucky. You'd be a lot better concentrating on your available options now, rather than potentially getting worked up over Bristol.
