Woolworths - I expect better

I purchased two Country Road cushions, online on the 27th of June. On the 1st of July I received 2 cushion covers. I then called the Customer Service Centre and told them that I received the cushion covers , but not the inners. The advert online advertised cushions, no mention that the inners were not included. After several more calls, after being told that my query was being investigated and has been escalated, I was told that the cushions were supposed to come with inners and that someone from the warehouse would contact me regarding delivery. I was told that there was a problem with the supplier. I have yet to receive a call from the warehouse. I last called on the 11th of July. My question is why sell an 'incomplete item'. I paid for this item, now I have to be the one calling several times to receive the other part of the item. Customer Service - take the inners out of other cushions the same sized deliver it to the client. I have never experienced this from Woolworths, especially not Country Road. I sent an e-mail, no response. So here I am trying to get this query resolved. My reference number : ***6
