A couple of projects:
1) Went to book flights with a United credit that expired in January of 2025. Email confirmation & app both show that date. When I tried to book a flight for October, says it's beyond the travel date. Spent over an hour on the phone with United, and it turns out that I'd used a $75 credit (on a $10k reservation - trip for four to Turkey) & that reset the expiration date on the back end, with no notice. United was able to fix it, and reissue manual credits (which, ironically have a longer expiration), but if I hadn't noticed this or waited longer to book flights, they may have expired.
2) My doctor's office made a typo in their bill (spelled the name of their hospital incorrectly?!), which caused my insurance to consider a bunch of labs out of network, and they paid zero. I've since paid, because we couldn't figure out what happened. I've made numerous calls to the hospital & my insurance yesterday, and I think we have a solution. It's a $1760 bill, so I'm very motivated to keep chasing it until it's resolved.
