PASSING THE BLAME ON TO THE CUSTOMER?

On Black Friday I spent 9 hours trying to purchase a mini hifi on the Hifi Corporation website only for it to crash 50+ times. After numerous calls and emails I finally managed to get to the screen where I entered my c/c details only to then have the system crash yet again. Upon getting the site back up again I went to see if my order had gone through which indeed it had and the system therefore wouldn't allow me to go into the order at all from this stage so having an order number I assumed I was now done. Of course I never wanted to try again and therefore pay twice either so after sending an email enquiring as to what to do I left it. On Monday I called them to enquire about my order only to be told it was Cancelled due to none payment... I have since spent hours on calls and emails only to be insulted that I don't know the difference between putting an item in the basket and actually checking out! This is totally unacceptable that they are taking no responsibility for this and basically I now just lose out after spending an entire day on the website trying to make this purchase. Disgusting customer service if you ask me and I hope everyone I tell will agree!
