My iStore NIGHTMARE

I'm writing this review with a lot of frustration! I successfully ordered two MacBook Pro laptops online. The money was debited from my account but I didn't receive the order confirmation nor does the order appear in my order history. This was yesterday (Sunday) so their call center and Live chat were not operational.. I tried direct messaging them on twitter but there was no response. I called them this morning and explained the issue, I was told the order does reflect on their side (as "Pending") the money hasn't cleared and I should call my bank. I then called my bank and they referred me back to the iStore because "the processing needs to happen on their side." Called the iStore again around 10am and the lady I spoke to since said they'll call me back, the accounts dept are yet to check.. This is really frustrating. I also found two tweets about the same issue on their profile, meaning this is something they are aware of but I don't understand why the first consultant referred me to my bank instead of trying to help.
