I flew JFK-NRT and then HND-LAX-JFK, with the transpac legs operated on ANA metal but ticketed on a UA codeshare.

The United-metal LAX-JFK posted very quickly to my account, but the ANA legs (i.e. the big mileage ones I need) never did. I called up United MileagePlus to inquire, and was told they were missing my ticket #, so I provided. 2 weeks later, and still no miles... so I called up again and they informed me the the mileage was in "dispute" between UA and ANA.

I really need the miles to clear for some travel I have coming up, but UA is of no help beyond telling me "it's in dispute". Does anyone have advice for how to move this along? Thanks for listening!
