No delivery on stipulated date

I bought some items on line on the 2nd of March, that I needed to use on the 7th of March. On Thursday the 5th I was told my order will be delivered on Friday, on Friday I called to find out where my order was and was told I would receive it before end of business. I did not receive the order, I called the courier company Saturday morning to find out when they will be delivering and they told me it would only be delivered on Monday, I no longer need this delivery, I had to go to makro in riversands to buy the items so I need the order canceled and my money back.
