Disappointed and want my money back

my order number is ***, this order was made 25 July 15 and paid on the 25 July and confirmation was received on the 27 July confirming payment and that the order can expected on the 18 August 15. On the 05th August, i received an email from Jamie-Lee Joseph, on the 05th August that you cannot assist as the supplier has ran out of stock before my order could be fulfilled and I must send through my account details so that the refund can be done. I sent my details on the 05th and also wrote an email that citing that i would have appreciated a courtesy call which never came. I called the next day as your emails do not have automated response, so i dont know whether she did receive my email or not. I called again today, and I am being told my refund will take anytime from 48 -72 hours which i am not impressed with. I am not the one that cancelled the order but you are the one that cannot assist, please pay back my money today as i am not sure what is hold up as you cannot assist. I am disappointed to say the least and i will definetely be using your competitors from now onwards.
