No delivery on online order!!!

Absolutely beyond frustrated with your online department! I placed an order a month ago on your website! Expected delivery date was 16 May, by the 22nd I called to follow up, was told it would be delivered by the 26th! 30th I called again as no delivery has happened to be told latest Thursday 1 June! Yesterday I received a mail stating that my “incident” has now been RESOLVED! No it has not, as I have not received my goods that payed or a refund! Online it shows my order is “completed” when I call the call Centre they tell me it will be delivered that week! I tried to do a refund and my order is not even reflecting to select a cancellation! I get put on hold and no one can seem to help me! This is via! Facebook, Email and actually talking to a person! By the looks of things scrolling through hello Peter this is a common issue! DO NOT ORDER ONLINE from them!
