Updating information, only allowing me to sighn up for student discount

[Shutupthepunx]

Hi, 

i lost my debit card and then got a new one, I'm trying to change my payment information but whenever I click the option to "change info" it leads me directly to a page for signing up for the student discount. I recently graduated so I am not eligible, but it won't let me update my card without bringing me there. Please help )-: 

thanks,

nina
