Charged back pay by my therapist

Back in 2021 I started going to therapy in Arkansas. The clinic told me that they do not accept insurance so I’ve been self pay for all my visits. Earlier this year my therapist tells me they’re contracted with my insurance company and now I owe back pay because they’ve billed all of my visits from 2021 until now to my insurance. I didn’t really know what to say so I just agreed and paid what they said I owed which is around $300. I asked our insurance agent at work and she said they can do that because they got contracted back in November of 2023… they never told me my insurance would be billed, and I never signed a new consent or anything. I just received an email from them today (literally written in comic sans wtf) and they are saying I owe almost $300 more! My original consent form signed in 2021 states their fees but it doesn’t specify whether that’s for cash pay or insurance. They also have a clause that says “it is your responsibility to know your insurance policy and to notify office of any changes”. They NEVER notified me of any changes. Is this legal?

Thank you in advance for any help.
