my code wont redeem says error has been reported try again later any ideas

Hi all, I am getting the same code (0x87dd0019) in relation to Forza 5 Day One downloadable content (using the code supplied in the box). It says installation stopped, and then gives me this error code.

Any ideas? Have tried to redeem the code again, but it says it has already been redeemed. Anyway to remove the failed download and start it again?

Same issue here. Tried on the website, get error code.

Except:

Tried on console, says try again later. Tried again later and my account is now locked from making purchases. For trying to redeem a code.

@ngocphi No initially it came up with "Sorry but an unexpected error has occurred. The error has been recorded and we will investigate. Please try again later." This message has come up about 15 times over the last week whenever I try to redeem the code.
Now when I try to redeem the code, after chatting with support, it says, "Something happened on our end. Waiting a bit might help."

I have done that all ready and it wont show the game at all and when i try to redeem the code again it says codr has all ready been redeemed

it´s rigth, look this is what is says... "An unexpected error occurred. It has been registered and we will investigate it. Try to redeem the code later."
