Appalling delivery service

After placing an online order for a desktop pc and monitor, pc world made sure I would never shop with them again. I paid extra for next day delivery and the order was delivered, well half of it, the monitor arrived but the PC tower was lost in transit and the Delivery service tried to get me to sign for a delivery label only. After days of phone calls to customer service at PC world they then informed me that their policy is that no refund or another PC tower would be sent to me until they find what happened to the one that was lost by the delivery company. A phone call the following day informed me that this investigation could take up to a week before another product would be sent out, I'm writing this review to warn any potential buyer from PC world, they are not a good choice and their customer service is awfull, shop elsewhere because if they loose your item before it's even been delivered you won't be getting another one sent to you for a long time.
