This,

And,

Not only are the dates different but the codes used are different. Why is that?
Have you ever used Xbox ?
How are the codes different ?
There is only ONE code, tried on two different devices, one MacBook pro and one Xbox.
The dates are different yes because the screenshot I took to prove this was taken at the time of me making the post.
The code that I specifically posted screenshots for are error codes... One is for you not being in the region the code was bought in and the other is saying the code has been used.
The code that says you are not in the right region is the one you took on the 20th of November which shows that the code was in fact valid. Your screenshot from yesterday shows the code was used.
And no, I do not use Xbox but it doesn't take a rocket scientist to look at an image and see something is wrong.
Does the region affect anything ?
I've redeemed and sold many currency Xbox gc's and they have always worked fine (region didn't matter).
As I said before I'm a reseller.
I found a buyer for this GC for $24 (I had previously bought it for $20 from librty). I had a Skype Screenshare section with the user and in fact the code did not work. (It was also the user who tried buying it that sent me the same image - the xbox one). I eventually refunded him.
I actually have no idea of what is going on right now. So you're saying librty code was valid ?
I tried redeeming it with the user and it DID NOT work.
