WORST ONLINE SHOPPING SITE

I placed an order (3 items) on 25 November (Black Friday weekend), because they really had some great deals and I was impressed. I had paid for the goods and sent a confirmation email and all was in order. On the 29th of Nov, I received an email to say that 2 of the items will not be delivered "due to a stock issue", however I received an email to say that all the items will be delivered, I called for days and no answer. I emailed umpteenth times, no responses. I then received only 1 item, which I then returned. I emailed to say that I would like a full refund for all the items, still no response. I called and called, eventually I got through on 21 December, almost a month later! How pathetic! I received a refund for only the item that got returned, no refund for the items that were not delivered, that same day I emailed to say this and .. yet again, NO RESPONSE! The worst part of it all is that, the item that apparently had "stock issues" is still for sale on this very date (in the size that I wanted to order), and still on this very date I still have not received the rest of refund! I have tried to call this morning, at least 4 times. This is absolutely pathetic and I will never purchase on this site again and I have not and will never recommend it to anyone.
