2 Orders in a row no delivery

Order references: o ********** 14 & o ********** 29

My last 2 orders I placed with Woolworth's online have not been delivered. The first one I had to spent many hours trying to resolve to in the end be transferred to the store manager handling the order. His response: "My order is ready to be dispatched for immediately delivery" - this in the late afternoon where my delivery slot was scheduled for the morning.

Can you please clarify if the chosen delivery slots are just something you hope is going to happen or are actually committing to them? I have no problem with delays from time to time but at least send me an automated email/sms or whatever.

My second order was scheduled for delivery yesterday and is still pending. Just called customer care now who promised me to call me back in 5 mins... that was 15 mins ago. From my 1'st order issues I called 3 times everytime ending up with someone will get back to me which never happened. To be clear - over my last to orders I called customer care 4 times with promises to get back to me which never happened.

I am leaving soon on holiday and I suspect what was supposed to be a Christmas present is now not going to happen.
