I contacted them again. My earlier request had been denied by the partner. They now resubmited my request to the partner...

They say doing the same things results in the same results, we will see what happens.

What I find odd is that the partner needs to approve the request. I suppose this is an approval just to confirm that I actually flew on the flight? All the other necessary information is on the e-ticket and boarding pass I provided them (like FFnumber, booking class)
