Poor Service - Online Orders

Placed an online order 18/12/18 for delivery on 22/12/18. Paid, confirmed stock, tracking says out for delivery. No delivery, no contact. Called the call centre 24/12/18 at 08:15 and the response was we will contact the courier and come back to you. Zero response. Called the call centre again at 13:00 same response and a promise that a supervisor would call back again within 10 minutes. No response. Called the call centre a third time at 14:00 spoke to a senior manager who stated that they needed to contact the courier. Really this is shocking service and responses from Woolworths. This purchase is christmas presents and it is unacceptable that there has been no delivery since I selected a specific delivery time 10:00 to 13:00 on 22/12/18. We spend thousands of rands each week with Woolworths online and expect a better response than "we will check and come back to you"
