Appalling service

I placed an order with Woolworths online more than a week ago. I booked and paid for a delivery time slot for Tuesday (5/9/17) between 6-8pm. This time came and went with no word from Woolworths. I then emailed as well as phoned their customer service. I was promised that the driver would arrive last night with a part of the delivery but once again no show. She also said that she would phone me back within the hour to communicate the second part of my order. I am still waiting for her to phone. I also placed an order and paid for delivery on Wednesday (6/9/17) time slot 6-7pm but once again the time came and went and NO SHOW. I have phoned and emailed and no one has answers while I wait for R800 worth of items and paid R100 in delivery and no one could care to help me as the paying customer.
