NO stock, NO delivery, NO communication AGAIN

Placed ordered&requested same day delivery&paid the additional value for this service (14/042016) as this was meant for a gift for my sisters bday. Arrived home&nothing was delivered. I sent an email advising them of this&requested some feedback. Also check my order status&it said: in progress. Was expecting some feedback as I saw their times are until 22h00 on weekdays. This morning I still had no reply so I sent another email requesting feedback. 1 hour later still no reply. I checked the status&it said: at warehouse. I decided to call&was told that the supplier no longer had stock. This is completely unacceptable. 1st bcoz the item was suppose to be delivered YESTERDAY & not one person had the decency to advise me that this was not going to happen. Clearly not one system gave a warning sign that a paying customer who PAID EXTRA for same day delivery didnt get the delivery. 2nd is that the call centre agent whom I spoke to didnt even seem phased that this had happened. She did the usual apology but its as if she is so tired of having to repeat herself that the apology was meaningless&the lack of service given was not a novelty.3rd I DONT HAVE THE ITEM&its not alarming to them
