No Delivery of Goods and Passed From Pillar to Post

As I am writing, I am holding on a call for Woolworths to come back to me with feedback regarding my online order ( 10 minutes and waiting - I can hear them chatting in the background) . This has been going on for 4 days. Delivery was supposed to take place on Friday between 10h00 and 13h00 and did not arrive with no communication that it would not arrive. I then called customer service who phoned the branch responsible for dispatching the order and Customer service came back to me saying the store did not know when or what day they would deliver. I then called Head Office and Mario called me back. He told me the delivery would arrive on Saturday or Sunday. On Sunday I called the store who said delivery would not be made on Sunday and they promised me delivery on Monday between 10h00 and 13h00. I am still waiting. I decided to phone the store, they put me through to their online people. Someone answered, asked for my order number and then left me on hold for 15 minutes ( this is where I started my complaint - see top of mail) - putting the phone on the counter where I could hear them chatting and then cut me off. He called back to say the order would be delivered today. It is now 14h00 and no sign of Woolworths delivery
