I am losing faith in Microsoft ability in Xbox Live

Now days my Xbox Live is becoming a piece of scrap. Two months back I was facing issues with friends list for more than 2 days. Since then I had several issues with party chat. Now when I tried playing NHL 2015, it broke down all of a sudden. I tried to login again but it is providing me several other options for creating new profile etc. I think I have lost HUT game on NHL 2015 which I had bought by investing more than 300 dollars. I am losing in Microsoft ability. Please provide me solution for this issue.
