Black Friday Special - Playstation for R185

Black Friday Special - Playstation for R185. I was on the site before 12. As soon as it got closer to 12, I kept getting an error from the site. I tried until 3am and was not able to progress through the options to make the purchase with out an error. I feel like Fnb should have catered for the influx of visitors to the site an app and handled accordingly. Also don't understand how the item was sold out when the service was down for this time.
