Who Me Too'd this topic

My spotify premium account was working fine until earlier today when it automatically logged me out. I was unable to log back in afterwards, as it said that my username and/or password was incorrect (which I am almost 100% positive that it was not). When I tried to change my password, it said that my username did not exist. I sent an email to Spotify support but just received an auto reply suggesting to come back to this forum. I replied back to that email and have not gotten any email back. 

Why is my account no longer accessible? Will I still be charged even if I can't even login to my account since it is presumably "nonexistent?"
