A few days ago I bought a Microsoft surface , the product is amazing overall but my Skype has been playing up . I try to call one of my friends and it keeps ringing but never gets to them. They ring me and I press the answer button and it automatically ends the call . I thought it might have been my Wi-Fi playing up but I tried Skype at other peoples houses and it did the exact same thing , I was wondering if it was my tablet playing up, or my Skype or even my Wi-Fi.

Thanks for your time.
