Premium Payment Failed

[vul_pixels]

So back in December there was a three month for the price of one deal going on and I bought that,and that worked out fine,no issues. Then I received a gift card for three months of premium so I was going to use that as soon as my first spotify premium subscription ran out. I added the card on Feb 25 and there were no problems,it said the payment went through. On March 6,my first spotify subscription(from Dec) ran out so I went to get premium using funds that were already on my account,but I can't find them anywhere? I tried to make the transaction again just in case but it said the card was already used. Did I mess up trying to pay before my subscription was up?
