Disappointing Service from Woolworths Online

Absolutely shocking experience ordering online from Woolworths - Placed an order on 02/12 - Received an email to say delivery would take place between 7 and 13 December. By 14 December parcels still hadn't arrived. Sent email, no response. Called their customer service on 15/12 - Was told there was a problem / backlog with the courier company. Promised by the consultant that delivery would be on 16/12 between 2pm and 5pm. No delivery happened. Still no follow up or communication from either Woolworths or their courier partner. Phoned again on 17/12 - Consultant gave me the same story ( I think they just read from a script) and she informed me that the courier company don't deliver on Public Holiday, so consultant from previous day either just told a lie to placate me or doesn't know what she is doing. I do a lot of online shopping and this is by far, the worst experience ever and so disappointing. Woolworths you need to up your game and your customer services.
