I got double charged for a similar situation in summer of 2019. I had to swap out a car due to a mechanical issue half way through a trip at a different location than where I rented from.

I got charged 2x. Called 3 times and never could get an agent to fully understand my issue even after escalating to managers each time. I got promised a refund once but it never showed up. After over a month of fruitless calls I did a chargeback.

I will never use Hertz again. Criminally incompetent scumbags running that company. I suggest you send a final email for a paper trail and do a chargeback if they continue their incompetence.
