You may as well wait unti, results day, and then just turn down your place when you get your AS12 letter in the post. Or just ring and decline your offer on Thursday.
Admissions tutors are very busy over the next few days so its probably best not to harrass them in order to withdraw as you have lots of time to do so after this week.

Have you considered calling on results day to defer your offer instead? Then you could attend your course in 2009 instead, without having to reapply.
