Continuous lies

I purchased appliances and a set of pots at Makro online on the 08/12/2015 and their promise is that items will be delivered within 3 -5 working day. according to my experience that is all a lie and because up until today (22/12/2015) I have not received my set of pots and the other appliances were delivered on the 16th/12/2015)because I asked them to cancel the order and refund me so that I can purchase these items at a store where they value their customers. I was initially promised that I will get my pots on the 18th because the store will get the stock on the 17th but everyday a new consultant comes up with different lies. one of the consultant by the name of Kelvin even told me that Barloworld is responsible for non delivery of my pots which does not make sense as I am a Makro customer and their internal issues have nothing to do with me. I would really appreciate delivery of my items today or my money back today as the 7 working days of waiting for my refund is not acceptable because they have kept my money for too long and they still continue to make excuses. Makro is big company and they have lots of branches where they can get the pots from to make the delivery on time.
