So ombudsman can be for “petty” things, like the belt of my e-bike, but also for much more “serious” things like political corruption, vote scams, etc where I imagine Congress might be correct. As en.wikipedia.org/…/Ombudsmen_in_the_United_States clarifies though there are ombudsmen dedicated to agencies but also state level or even city and county level. So I imagine the more precise you are picking the right one, the more likely it’s going to be treated, efficiently or at all.
