Delayed Online order

I placed an order on the 2nd of December and I had the option of choosing of which delivery date and time suits me and I chose the 4th of December between 10am and 1pm. The 4th of December came and my order did not come and no one bothered to contact me to inform me what was causing the delay. I had to call in myself mind you I was on hold for like 15 min 7 minutes each time as I hung up before I could get through. I spoke to a consultant who seemed shocked that no one contacted me but they had to source the items on the order from different stores that’s why it was delayed and he assured me that the order would be ready by the next day. The next day came and no one called to tell me what the holdup is. I have paid for my order and they have an obligation to deliver my order, I tried to call the call the call center 4 times to inquire on the whereabouts of my order, each time I was on hold and I had to hang up can you imagine being on hold for an average of 6 minutes on each call and still not get through. Today it’s the 6th of December I am fed up with Woolworths online and I am tired of calling Woolworths and I will not be wasting my airtime, if you can’t deliver my order let me know and refund my money. The service has been appalling I am quite disappointed to be honest.
