Failed to deliver, do not use them

I placed an order online on 03/09/2015 and paid an express delivery fee so that my order would be delivered the next day on the 4th. I waited and waited but my order never arrived. So at around 5pm on the 4th I called the call centre and the lady said the courier was probably running late and I shud wait some more. But it never arrived. On the 5th when I called they told me they were more than happy to give me a refund when what I really needed was my order.
