Wasn't being rude. First of all, was trying to help. You didn't say you already had charts, just not the ones you want. If you wanted an OXFORD specific approach chart, you should have said so instead of getting all butt hurt over NOTHING.
Secondly, was simply pointing out that nobody is going to use email to contact you unless they already know you. It is a simple fact of any anonymous message board. Are you new to this place called "The Internet?"
Good luck with the Arik assessment. If you think an attempt to help you is rude, you might want to bring some thicker skin to the interview.
Oh, and lastly, your grammar on the first post was atrocious. Apparently when you get offended, your grammar improves. You should stay pissed off. It suits you on a basic level. (THAT PART WAS RUDE...FYI)
