Microsoft's Surface hardware is really great, but that doesn't mean it's perfect. Sometimes things can fail, requiring you to contact Microsoft's support service for help. Your issue might be solvable through software, but other times, you may be required to send in your device for repair or replacement.
Regardless of the issue, we want to know how your experiences with Microsoft support have gone in the past. Have you ever needed to contact Microsoft support? How did they handle your request? There is a related thread in our forums right now.
I've contacted them a few times regarding issues with a couple of older Surface devices, and both problems were resolved quickly. The first issue I had was with the webcam on the Surface 3, it simply failed and there was nothing I could do within Windows to fix it. So, I contacted Microsoft support, and they set me up for an exchange pretty quickly. The other time was with a Surface Pro 4, which was suffering from screen flicker issues. I contacted support, explained the situation, and they set up an in-warranty exchange that took a little under a week.
I know not everyone has had experiences that went as smoothly as mine, so if you're someone who had a bad experience, let us know in our forums what happened.
