Most of the items ordered were no actually in stock, though the website indicated they were. So the order was cancelled.
Time was wasted by everyone because stock availability was not updated nor did it show when items were discontinued and not being restocked.

Sorry to hear that some items you ordered were out-of-stock. Unusually these were discontinued items that had been reduced to clear, sold out rapidly but not restocked. We were happy to provide a full refund on your entire order. Feedback like yours helps us improve our systems to make sure our website more accurately reflect stock levels.
