It's funny you should say that, because OP actually tells a more complete version of the story here [0]. Hertz did send them a new bill with a threat to send it to collections if it weren't paid.

Maybe still a win in the end because the incorrect charge was removed, but I get really uncomfortable with how casually people recommend chargebacks on this forum. They're not intended to get you out of charges that the other party can prove you did agree to pay.

The context here was a charge that should not be paid…

Bundled with a bunch of charges that were, in fact owed. OP disputed the whole charge (probably because that was the only option), but it's important to know that Hertz did come after him for the rest of the money.

Right: as you say there probably was no other option -- OP was in a bind because all the charges are packaged together. There wasn't really a neat solution to this, except how OP played it, which could have ended up going badly wrong.
