Student Discount

[Fiona50]

Hi, I wanted to sign up for spotify using my uni email. but somewhere along the line I seem to have duplicated my account and now i have 2 usernames, of which the one it logs in with won't allow me the student discount as it says the account is already registered with another account. I am frustrated as i have 2 usernames but never gives the option of which one I want to use. Please help.
