I was recently sent an email by XBOX saying I had received a 'FREE GIFT' that granted me a Redeem Code to enter.
I entered my 'Free Gift' and it enabled me to have access to a vast majority more selection of 'Specialisations' in HALO 4.
I have just re-checked my 'Specialisations' menu to see that they have now been taken away and I only have access to 'Wetwork' and 'Operator'.
Surely XBOX wouldn't of given me a gift for 5 days.
I have contacted the 'Chat' Service, where an Ambassador took me through steps to 'Re-download' the Alpha Pack, but it hasn't worked; so they gave me a link to write my problem here.
Thanks for anyone that can help!
