Non-delivery of order without feedback to customer

I placed an order on Monday 7/09/2015 with a delivery date of Tuesday 08/09/2015. When by Wednesday I hadn't received anything, I followed up and was told 1) the order was cancelled and the the explanation changed to 2) the payment wasn't successful. I provided them with proof of payment and was promised the delivery will take place on Friday, 11/09/2015.<br> On Monday morning, 14/09/2015 I again queried why I still didn't receive my order, and was told again that the payment wasn't successful. I requested to speak to a manager, who finally returned my call after 2 hours. She informed me that their supplier advised that they ran out of stock and can therefor not deliver my order.<br> I also sent a mail over the weekend to query the non-delivery, and I'm still waiting to receive any comment/feedback.<br> <br> I think this is shocking service, being told different (incorrect) reasons why there were delays with my order, having to constantly follow up on the order and not receiving any genuine apologies. It also left me with an embarrassing situation not having a gift when I needed it.<br> <br> This is a competitive environment - it's easy to shop elsewhere in the future.
