Fine Repayment Emails

My situation is a little different than simply leaving a contact early. I started the RN residency at Parkland in Dallas in Feb 2022. Due to some reasons out of my control I had to take time off (at least a week) which they wouldn't allow for.

Due to this, me and the manager of my floor talked about options and she told me I could leave the residency all together and decide whether I wanted to join the next cycle's cohort, essentially restarting the residency. Or I had to take the 2 days of time off they offered, which was literally impossible for me to do because I needed more time. All of this happened in April 2022, so I was not yet on my own and still working with a nurse preceptor.

I decided to take the option my manager offered and my residency contract was voided, I have emails with all this proof btw. 

When the time came to decide if I wanted to rejoin I had decided that I couldn't due to the same reasons as why I had to initially take time off. My nurse recruiter sent me an email saying I had to send an email saying whether I accepted or declined the new offer to start the residency over again in July and had attached a new contract to sign.

I politely declined the offer and now I have been emailed twice, one last May and again today, about repaying a 10k fine that was owed.

After receiving the first email, I reached out to their finance team and explained what had happened and the lady seemed very confused about why I even received a fine email. Said she would research the case and get back to me. Never heard from her again.

Now it's Nov, I am receiving another email from another lady who I have never spoken to from their finance team saying I still have a debt of 10k to pay with no other information. What should I do?

I am being advised to not reach out because they are using scare tactics to try and get me to pay, especially since I already explained my situation and they didn't seem to try and resolve it back then. But I just wanted to hear from other nurses who may have had similar experiences or know more about Parkland's policies specifically. TIA!
