Someone linked my hulu to their spotify without my permission how to i figure out who??

[Nixifer]

I canceled my hulu subscription last month and i just got an email saying i have hulu active again with spotify with a student premium discount... except i'm not a student and i currently have free spotify i do not have a premium service at all. and the email i use for spotify is different than the email for hulu. To top it all off i tried to see if my email for hulu had an account on spotify and it says my email does not have an account active on spotify. 

I dont know what to do about this, i feel like someone linked my hulu account with their spotify and now i'm worried someone has my information and/or will be charged for this service when i didn't request it. I've tried to reach out to spotify but i have not been able to get in touch with anyone...

has anyone ever had this issue??
