I canceled/requested a refund on my account on the 28th of October 2012 and I was told that I will get my money back within a week. It's the 5th of November today and there's still nothing in my bank account.
I believe they meant a "working week". If your refund was coming from Ireland (likely), it was a Bank Holiday here last Monday. NOTHING gets done on a Bank Holiday Monday or Tueday.
I'd hang in there, you'll probably have your refund later today or tomorrow.
