Last week, car battery died. Went to dealership, got a new battery. Today, Surface Tablet has defect with headphones. Went to Microsoft Store, got a new Surface Tablet. All this time, I have been raving about my new Surface so much I forgot to test out the headphones haha. But I went to customer service and they replaced it immediately. My advice is to go to the Microsoft Store if you want good customer service. Microsoft is too busy to handle phones (Amazon is good on that, not Microsoft). Plus, plus, they really then need to ship it out to retails to handle customers. Phone services sucks for tech business - unless it is Amazon.
