My 10k miles didn't show up, so I sent an email to customer relations. They came back to me after aprox. 10 days with the following:

Hi there, so sorry it has taken so long to get back to you. I just added the
10k to your account. You should see it in there the next time you log in.

Thank you, Sarah O.

Now I'm only missing my Elevate points, but I don't know if it link up properly.
