Well, I've got a very impressive tale of customer service to share. (I'm a Yank, if that helps orient this tale.)
The DC41 was bought as a refurb from meh.com a few months back, and it had a 6 month warranty. While trying to figure out the problem I went through the online troubleshooter at Dyson's site, and there's a tiny survey at the end of it, with a space for comments and contact info. Since I've never seen any response from those things before, I very nearly didn't enter my email address, but I did, and within a few hours I had a response asking for more information and photos of the problem.
I didn't see the reply until near the end of the day, but I did respond with details on the purchase and the photos. That was around 10pm. When I got up the next morning (Sunday) I had three messages from Dyson that were sent between 2 and 2:30am! (The messages indicated Dyson support is based out of Chicago.)
The first two were automated messages. The first thanking me for registering my warranty, and setting the warranty start date to the date it was delivered, not the purchase date, which was two weeks earlier. That was a nice touch.
I'm glad the problem showed up now, since I've got a little over a month left on the warranty.
The second message was thanking me for scheduling a service appointment for my problem. It also had a UPS store finder link, and instructions to take the DC41 to the UPS store, give them the included number, and UPS will pack and ship it to the nearest service center.
The third message was a personal reply to the ongoing thread that started with the comment page, saying the nature of the problem needed service center attention, confirming the return instructions, and saying the typical turn around time was 10-14 working days, including return shipping time.
Monday my wife took the DC41 to the UPS store around the corner. It took the store staffer a long time to figure out the procedure, but they took it off her hands, and gave her a tracking number.
When I check the tracking number the next morning (Tuesday), it said it was out for delivery, which seemed a little unbelievable. Then later in the day when I checked it, it said it was delivered at 12:09pm - to the other side of Salt Lake City. Apparently the nearest Dyson service center is about 20 miles away.
All that was impressive enough, but a couple of hours later I got an email from Dyson saying that my vacuum was repaired and on the way back to me! Maybe the Salt Lake service center doesn't have much to do, but it was less than 2.5 hours from receiving the DC41 to fixing it and having it ready to ship back!
Sure enough, the DC41 arrived today, Wednesday.
Color me impressed!
