I fly EWR to MNL alot and usually take the long, all United route

On the return, I usually apply a RPU and it covers most, if not all legs

The return is:
MNL to GUM
GUM to HNL
HNL to EWR

I am most concerned with HNL to EWR. But in the past 4 or 5 time I flew this route, the GUM to HNL confirmed as well. The MNL to GUM is a short flight, so I dont really mind either way.

technically the GUM to HNL is not eligible for a RPU upgrade. But like the last few flights it always filled. The Rep on the 1k line, usually submits for it, telling me it might not fill, but it seems to always confirm right away.

So this time, I called like before. The rep said it is NOT eligible. I said I realize this, but can you submit it and try? He refused. I asked for a supervisor and she claimed it is NOT eligible and read me the same line over and over again. She claimed there was NO way to submit it. I explained that the last few times the reps all tried and it confirmed. I asked if she could look. She claimed there was no way to look. I said I can provide Confirmation numbers. She said, if that was the case, she would be forced to report all the Reps who overrode the system to give me an upgrade, when they are not suppose to.
I tried explaining that there is NO way 4-5 reps all did an illegal override. But at this point it seemed pointless and I didnt want to continue and possibly cause a handful of considerate reps to get in possible trouble.

Is it possible that all the previous Reps overrode the system to give me an upgrade??? Seems unlikely??

Sorry for the gripe
