After whinging and complaining here something positive.
My Surface Pro 2 was playing up lately, i decided to send it in for a check up. Especially since the warranty expires in a few days.
Monday online chat with MS support
Tuesday Surface collected by Couriers please
Thursday Replacement delivered
I think they have had no SP2 in stock so they sent me a refurbished Surface Pro 3, brand new keyboard, stylus and charger. Blown away with this service.
Yes my experience with Xbox One warranty with MS was the same, Very good service.
