Redeemed a prepaid code but didn't extend my original subscription

I redeemed a 12-month gold membership prepaid code on Dec 2016, but my current gold subscription didn't get extended. Instead, the prepaid code added a new subscription to my account. So I have 2 subscriptions now, the original one expires on 6/23/2017,
and the new added one expires on 12/3/2017.

Why do they overlap, not stack???

Need help redeeming my xbox live code

I tried redeeming the code in my browser on my computer using these instructions, big mistake. It said "thank you, you redeemed your code" and then exited me out. No gamertag registration whatsoever. I thought the whole point of redeeming my code was to create a gamer tag, but no just exits me out. I then tried redeeming my code on my xbox (so that I could create the gamer tag) and it said "sorry, code already redeemed."

so what the... what do I do now?

 

Didn't get money

Hi I bought a $25 prepaid card and didn't get the money it showed me that the code was already redeemed but I didn't get nothing.Then I checked my order history and it said I had had redeemed $0.00

 

Hey there!

Your subscriptions shouldn't be stacking, once your current one ends, your next subscription should begin. If you have concerns on your current subscription you're welcome to reach out to
Phone/Chat support for clarification on your current subscription status.
