Lying about commitment to deliver order

I am highly disappointed and disgusted at the moment by the lack of service I have received from Pick 'n Pay since Friday.

Order number ********** 201 was supposed to be delivered 01/12/17 between 11:00 and 12:00, It was brought to my attention that the order was never delivered. At no stage did I receive a SMS, e-mail or call to state that they are running late. This is now 04/12/2017 and still no groceries, after I was told on Friday afternoon that it will be delivered 07:00 AM.

I followed up once again at around 08:30, after being on the phone for more than 18 minutes, I was simply told that the hub manager, Milicent said that she never received an order for us for delivery. Please explain to me then, if the order was not dispatched to Milicent, how on earth would they have the order delivered 07:00 AM today? The only assumption I can get to is that it was a blatant lie to get me to stop complaining. The lack of feedback from them is also shocking.
