Woolworths process my refund immediately

I purchased shoes on the 2nd of November in the morning on the Woolworths online platform. I selected and paid for an express delivery. The delivery was supposed to arrive on the 3rd of November. I called that Friday morning to check on the order after I got an sms that said my order der will be delivered at a later date. When I called they said there was an IT glitch and the order would be delivered on Saturday. I decided to cancel the order because I needed the shoes on Friday. When I called in again after the weekend, they still hadn't processed the cancelation. They said I would get a refund in 7- 14 days. I didn't get it. I called again to check on the refund, they told me that they hadn't processed it and I would have to wait another 7-14 days. I called again today to check on the it, the refund department still hasn't processed the cancelation and refund. I was told I'd have to wait another 3-5 working days. I'm so disappointed. I expected more from Woolworths. I'm actually angry because they have proven to be very ***********. Nothing works. All they online departments are ***********.
