Psychiatric clinic that I briefly went to is now trying to collect on two visits from January. The clinic closed in February under very weird circumstances and I only found out when I went to pick up medication and the prescribing doctor didn't send it over like she promised. It's now been reopened apparently.

I see the two visits on my personal calendar, and EOB on my insurance. I've scoured my credit card statements, but don't see that I've paid them for those visits, but then again, I don't see evidence that I've paid them for any visit, including ones last year (likely meaning that it was on a credit card that I had since closed and no longer have statements for).

Normally, I'd assume that they were telling the truth given that the people reaching out to me know too much to be scammers, but they've been acting a bit suspicious. They've been making spelling mistakes on the invoice they've sent. When I logged in to the portal, it showed that I had no balance due, until I informed them of this after which they added the invoice to my balance, but listing a doctor I've never seen, and the service dates were wrong. When I pointed THAT out, they said it was because my provider is no longer with the clinic and I wasn't registered in the portal at the time I saw her (also untrue, I see messages between me and her going back to last year). Finally, I asked for the clinical notes for the visits since I didn't see them on the portal and a history of payments I've made (to maybe trace it to which credit card I was using), and they just ignored those requests multiple times. They've been using the clinics old email address, but the number they're calling from is registered to some plastic surgery business that I can't find any info about aside from the business registration.

Is there legally something I can ask for them to show me before having to pay these debts? I'm almost inclined to let them send it to collections so at least then I'll know it's a legitimate provider. At the moment, it almost seems like someone hacked the email of a closed business and is fishing for anyone they can collect payment from based on some limited information they've found.

Maybe I'm being paranoid, but this is Florida after all.
