Not happy with Woolworths customer service

I think Woolworths online customer service is the worst. Had ordered something online and had to choose a suitable delivery date which I did. But the problem is there have no way of tracking orders and was told that they do not know where my order is. And for their sale items, for the first week of sale you are supposed to get a 10% discount if you have a Woolworths rewards card linked and they never even honored that promise and are sending me from pillar to post. Very disappointed atWoolworths as a brand I thought was better than that. They do not have proper channels to raise complaints, when you request to speak to a manager, they send you back to the call center.
