Bought a 2nd hand video card with 3 fans from Cex with a 2 year warranty. Discovered one of the fans had sheared off. Checked and found that it was still within the warranty. Brought the video card in for a warranty check. Was told, initially that it was determined that the damage was caused by the customer because the video card's case had been opened(I hadn't). Pointed out that if it had been opened I bought it off them in that state, seeing as it was a pre-owned product.
Later on told that the damage was caused by customer because "i had overpowered the card". Same thing, I hadn't because I don't overclock. Inconsistancy between reasons given shows they're lies invented to allow them to refuse to honour the warranty.
Cex are crooks, will never buy from them again.
