Woolworths has taken my money and not refunded me!

I am so disappointed in Woolworths! I spent over R600 on groceries (the dash app) and the groceries were not delivered even though it showed delivered. I contacted woolies numerous of times sitting almost 3hrs waiting online for someone to advise me on my order. After eventually getting feedback they just said I will be reimbursed and not caring about the inconvenience being caused. I called them on day 8 (working day) to find out where my money was for them to tell me you must wait 14 days. Guess what it's officially over the 14 working days and to date I have not been reimbursed. Woolworths has taken my money immediately and refuses to credit me back. How's that for customer service???? They are pathetic and I'm so dissapointed in their supposed to be good brand.
