Why have the optionto pick delivery times and dates when you ignore them?

<p>On 11/05/2017 I placed an online order with Woolworths SA to be delivered before 12:00 on the 15th of May. It is now 17:17 on the 15th and the order has still not been delivered. </p> <p> </p> <p>Why have the option to pick a delivery date and time when they are going to ignore it in any case. What was supposed to be a anniversary surprise for my girlfriend has now become a disaster. </p> <p> </p> <p>I have contacted their customer service and Facebook pages, and all I got was a message that they will escalate the matter to the right department. I find the service and response to be pathetic.</p>
