I ordered a refurbished Asus Vivobook and had a free named day delivery code. DPD messaged me with a one hour delivery slot on the day and it arrived on time. Initially I was delighted as the laptop seemed brand new, but after loading software I realised they'd delivered the wrong laptop with a lower spec. I called customer service and they arranged to collect free of charge the next day. It then took 2 days for laptop to be received at their centre and two more days to be inspected. They then contacted me to apologise for a warehouse error and allowed me to cancel the original order as I'd now found a new version of my desired laptop on sale elsewhere for only £20 more than my refurbished one. Money back in my account within 2 hours.
