Pay me back my money or give me the milk

I ordered milk on Monday online and on Tuesday I receive an SMS to say they don't have stock, I called the call centre spoke to a guy that said I must go to the store they will have stock, I got to the store at Columbine square the manager tells me there is no milk they have no stock for the 1.5 litres that are on sale. This morning I call the call centre so they can process my refund since Woolworths can't deliver their false adverti*****t they tell me I have to wait 5 day to get a refund, now I'm seating here without milk my kids can't eat cereal I don't have money for milk, I'm using my airtime to call the call centre that can't assist me, wow, did not expect that from Woolworths, not Woolworths 😱😱😱!
