Woolworths online nightmare

I order an item online on a Wednesday and made arrangements for a delivery same week on Saturday between 10am and 1pm. At 12-12:30 I was on hold for an agent to be available at woolworths online agent, I wanted to enquiry about my order because I was suppose to be notified when it' out for delivery but at 12:30 I still hadn't heard anything. When I finally got through to the call center I spoke to a lady by the name of Aphiwe and I told her my story and she put me on hold again to investigate about the order. After holding for 5 minutes she came back and asked to call me back as she was trying to get hold of the courier. At 13:55 I received an email (not a call) apologizing for the delay and mentioning the order will be delivered on Monday (2 more extra days). I called the call center several times, the time now is 15:38am, I still need to make arrangements for the delivery because I will not be available at the address and time specified when the order was made......this was my first online order and I will definitely not be making another one, this is a nightmare. I cancelled all my meetings that I was suppose to have around the time of delivery to make sure I was there when they deliver, they did not deliver and I still have to run after them to get an explanation and make arrangement. This is horrible service that I never expected from such a big brand as Woolworths. I wish they could have a competitor with better service because I would never buy any of their products again!
