i'm not sure what magic i was able to pull off, but when i called 3 or 4 years ago (pre pandemic, but around this time of year) my call was picked up immediately and the worker was really helpful. i was able to confirm i was registered even though property.phila.gov said otherwise and i was also able to correct my name on the property record, they put an incorrect middle initial on my record.

with it being 2 days before 2023 and the whole shitshow over property tax increases it's not surprising they're being swamped with calls right now
