It says that I will be put on a free 7 day trial.  HOWEVER,  "Sprint Customers: Users accepting a trial will remain on Spotify Premium and will be billed up to $9.99/mo and may cancel at any time." I am a sprint customer. I DO NOT want to be charged. I want to cancel my subscription. Why can I not? I clicked the 7 day trial on accident and was fine with it because I didn't need to include info, but now im being charged $10 when I don't even want it? Let me remove the subscription??
