Beta Code you sen't me is in use?

This is what I get when using beta code.
I received another email with a different code, but that one was invalid.

Hi there,

We've now sent out replacement keys to everyone affected by this issue. Please check your emails, and let me know if you have any further issues.

@iyagovos Replacement key worked. Thanks a lot.

i did mine through xfinity and they said i would get an email close to the beta, I didnt think they meant this close
