Woolworths haven't refunded me after 2 weeks - Dont shop online with them

I made an online purchase and after waiting for any feedback on the status I finally get a message to say they cant deliver as yet as the perfume ordered was non essential (which is actually a toiletry). SO I had about 10 essential clothing items in my cart and they couldn't deliver the other items and told me i had to wait or cancel. i cancelled the order and i have been waiting a whole 2 weeks for my money back. I have gone to the call center twice but after holding for 20 min on each try the call was diverted back again for me to hold on. Emails don't get responded to either and Twitter just says someone will be i touch. I need my money back and i want someone to call me back.
