I purchased this promotion on the 30th November.

Hiya,

First of all thanks for getting back to me so fast!

It was the 3 months Xbox live with 1000 free v-bucks for £6 - it said you will receive a code within 2 weeks.

Thanks again

Hi there John,

Thanks for the reply.

Quick question: when purchasing the promotion, were you new subscribers or users who canceled their subscription before 10/1/2018?

I did find the terms and conditions for the promotion.

• Valid only for new subscribers or users who canceled their subscription before 10/1/2018. Limit: 1 offer per account; credit card required. Not valid for existing subscribers . After promotional period, subscription continues to be charged at the then-current
  regular monthly price (subject to change), unless cancelled. Plus applicable taxes. Limit: 1 offer per account. Only valid through link in this offer, in all Xbox Live markets excluding Quebec. Credit card required.
• The bonus V-Bucks code will arrive via the
  Xbox message center within 2 weeks of purchase.
  

Hope this helps.

Are you checking the account that made the purchase? (I know, it seems obvious, but it can be overlooked by some)
