Light bleed on my monitor which was obviously not their faul but their handling of the replacement has been abismal. They did not even attempt to accomidate given me not having a monitor would mean I could not work and on top of that despite saying an absolute plethora of times that i want a replacement asap, once i no longer had a computer with an actual monitor, they still decided to contact me via email instead of phone (though they had permission through the data usage act) to ask if i wanted a replacement or refund! Now 6 days after sending it back and 7 after raising the initial problem, i have had to sort an alternative as ive been without a pc for almost a week and i find their idiotic question which has further delayed getting a replacement. communication was poor, the were un-accomidating and just all round did not handle the situation well at all, avoid like the plague
