Delivery almost a month not unfulfilled

Woolworths the brand is normally associated with absolute quality and customer satisfaction, I cannot say the same for their online service. It's been nothing short of dismal. So terribly hopeless that they should maybe get training from delivery company such as Takealot. I ordered my items a month ago, clicked that I wanted my items brought altogether and chose the relevant delivery slot. To my despair it was seperated and delivered on three occasions where I had to have someone wait a further two more times for collection. To add to the issues they didn't have most items in stock so they substituted an item without calling. I was absolutely livid calling immediately to get the correct item....it's now almost a month nothing. The other items which I did recieve a call for were delivered after many calls......horrid substandard service for money paid upfront.
