Online shopping worst service ever

I ordered a perfume online on order number: o***. When the order was delivered, I received the wrong parcel with order number o*** which was the slippers inside. I have logged this with the Call Centre on Friday morning and I was told that they will get back to me within24 hours and gave me the reference number: ***3, sent 2 emails on Thursday and logged a complaint on the website with absolutely no response. I am completely disgusted with this total lack of customer service. It's impossible to speak to anyone or get answers. It’s now 4 days since this was first logged and I still haven't received any feedback yet. How long does it take to check? I am now stuck with something that I didn't order and I don't where is my parcel. I have paid a lot of money for that perfume and it is a very urgent because I am buying this for my husband as his birthday gift. This is the opposite of the image Woolworths portrays and the promises it makes. Woolworths' is way to ***********.
