Bad online service

Ordered two items on their on-line sale on 29 January. Promised 3 - 5 working days delivery to branch. Received sms that there will be a delay due to high volumes during sales period, which I could kind of understand, although this is not supposed to be the client's problem. If you run a sales campaign, you need to make provision for high volumes?? Now 7 working days and this morning one of the items is indicated as "rejected" on my profile. According to customer services it is because it is no longer in stock?? Now, 7 days later, you realize this? Or is it because I bought the item for R110 and it is now advertised (still on sale) as R150? They can also not tell me when or even IF the other item will be delivered as they don't know if there is stock yet! Terrible service and not what I would expect from Truworths. I will never order online from you again.
