been given DLC codes that are invaild

If the code is less than 25 digits then it will need to be redeemed from within the game itself. If it is 25 digits then you should contact the people who sent you the email to let them know.

check ur recent history on the xbox under ur account, see if it downloaded right. if u don't see "Specialization Priority Alpha" then u might need to go to halo waypoint that the code was invaild on their forums for halo 4.

I rang the store and they would not give me a refund at all i even saw the manger activate the 3000 microsoft points at the counter Is there a way were microsoft or xbox send me a code with 3000 microsoft points because this code did not work everytm i type

The DLC has been delayed and Valve hasn't given an ETA yet.

well thats a given

prepaid dlc codes are region locked to the account region so if you get japanese code and you have an american account then it will be invalid

blackops dlc in particular is region locked to the physical region and the region it was purchased in
