I started using Spotify a week ago and I tried the 7-day premium trial. That day, however, my friend decided to upgrade our accounts to premium and we used her credit card, she listed and accepted me as a member but my account still wouldn't recognize me as premium user. At first I thought it was because of the 7-day trial, so I waited and it has passed the day and still, it is free. When I clicked the go premium button, however, it says that I already have a premium account, also on the browser. I have tried logging in and out again, reinstalling, rebooting my phone (an android, by the way), still it says my account is free.
