We haven't been open on a sunday for ages... where did you get the number from?
what was the problem in the end? I know that we arent allowed to credit the customer if its a fault caused by them, but when is it caused by the customer?
I like BT's phone system - where if there's a que - they call you back. we wouldnt get so many angry customers that say "I've been waiting 19999999 hours for you! RAR!"
