Hifi Corp false advertising.

I was looking for an external hard drive and found a 2 TB advertised by Hifi corp for R799. I travelled a significant distance to Hifi corp in Springfield only to find the item advertised for R799 was not 2TB as advertised but actually only a 1,5 TB hard drive. Furthermore, there was no attempt to rectify the situation and despite complaining to the manager, they did not even bother to take my contact details to provide feedback or an apology for the huge inconvenience incurred due to the false advertising. Shocking customer service and false advertising to boot. Shame on you Hifi Corp.
