Enterprise Rent-A-Car

I rented a car from Enterprise on Freemansburg Ave, Easton, PA. The time period was originally for 1wk (7/12/2021 — 7/19/2021). As it turns out, I had no means to return it to the original rental office 82 mi away, so I retuned it locally in NJ on 7/16/2021. Enterprise charged me the full 7 days instead of the 5 days I actually had it, AND a $500 fee for not brining it back to the PA office, along with miscellaneous taxes based on a 7 day rental instead of the actual 5 days.
This needs to be rectified.
