So for Christmas I got a $10 Spotfiy gift card that said I could choose what service I wanted. I was hoping that I could get the 3 months of Premium for $1 and I chose the "choose another payment option" so that I could use the money on the gift card to pay. But when I entered the gift card code, I automatically got 1 month of spotify premium for all the $10 on the card and now I can't get the 3 months for a dollar or even a student discount. 

Is there any way I can refund the money on the gift card so that i can save that for later, then be able to get the 3 months premium by paying through another method like a credit card instead??
