Delivery date pushed out by another week

Pathetic!!!! I ordered goods that were IN STOCK. My total value was over R500.00 which meant free delivery. My date for delivery was 3rd November. Which I was happy with. To my surprise, I can a cancellation email today, to stay one of my items is out of stock. I have just checked on line, and it says in stock. What happens next just threw me. My delivery date has been pushed out to next week of items that are also in stock. One item I needed today. I am so unhappy at the moment, and after calling them to cancel the order so I can do another order that will get delivered tomorrow, I have not had any more feedback. Oh I cannot wait for Amazon to arrive in SA
