Why won't the link to renew my student subscription work?

[Jbeaudry]

 Last month I was sent an email to renew my student subscription for Spotify. It gave me a link to click on and I clicked on the link and it took me to the information about the student discounts but it never had anywhere for me to renew my subscription or anything to click. I tried emailing a Spotify customer service and never heard anything back. I have now been charged the full $9.99 a month and at this point if I don't hear back I'm ready to cancel my  subscription because I am very frustrated. Someone help.

 Sincerely, a very poor college student
