Horrible online service

The online service is the worst i have ever experienced! They give you a delivery date and time and i placed my order accordingly as i assumed a reputable company like Woolworths would have their act together. Delivery date came and went without ANY update from them. After i queried it they scrambled to even find my order. I needed it by Tuesday, they promised monday delivery. I cancelled the order on Tuesday afternoon as i had made alternative arrangements. They promised a refund and even had me confirm the first 6 digits of my card. Today, 3 days later, they try to deliver my order!!!! When i checked my mail, they asked me, yet again to give my order number, which i screenshotted and attached to my query originally. Worst service ever! I do not recommend using their online service.
