They advertised a Rog Ryujin 360 AIO cooler as in stock on their web site , clearly stating 4 in stock . I ordered the payment of £200+ went out immediately. I monitors the website and sure enough the stock number fell from four to 3 then the day after from three to 1 and eventually to 0 I had assume my order was safe , 5 days later I checked their web site again and a message appeared in my basket out of stock . Absolutely unacceptable. I contacted them on the phone no answer , and through their web note option receiving automated response , dispute their assertions that customers would get a response within in four hours. I am now waiting for a refund , and will be easing an issue with PayPal . Never useOverclockers UK absolutely not
