Order not fulfilled.

My order was placed on the 5th of April, but is yet to be received. I was advised that I would receive a refund within 10 working days of 14th June , as my order was delayed for so long, however no refund was received. On 15th August I was advised via email that my order had been received that morning and was ready for immediate delivery. Nothing has been received to date, and my emails go unanswered.
