I've been using Spotify premium for quite some time without paying, and I'm not sure where should I report it.
Well, in the summer of 2016, I've been to Poland and I bought an Oringe sim card. At the time, there was an offer to activate Spotify premium for one month with that sim. But when I left Poland, I threw the card away. But the premium lasts ever since. I didn't fully realize until now.
It's not like I'm complaining, I love Spotify and I use it every day, but I have heavy conscience so...
