Good luck with Dell too.
They messed up one of my order before forgetting to deduct a discount advertised on their website. Never realized until item arrived. Called them and they admitted the mistake. But told me "Sorry! but we can not return your money. Can I offer you a free mouse pad instead?". I was like "WTF?" You admitted it's your mistake but you can't not return me the money?"
It was only a small accessories with few bucks, but that made me stop looking at Dell altogether.
