Hello, I have a Spotify account in the US. I have had Premium for Students since December 26, 2018 and pay $5.40 per month. However, on December 27, 2019 I was charged $10.81 and my account now says that its Spotify Premium with Hulu. I never made this switch and I would like a refund and for my account to be switched back to Premium for Students. Thank you.
