My question involves collection proceedings in the State of: California
I am a medical provider. I had left my previous employer unexpectedly and was not able to sign off on some patient notes. Initially, they demanded I sign a wet signature, but in the end, they said didn't need it, and are letting it slide as long as I do something else for them, that I have no obligation to do. With the riots and covid-19 going on, I haven't responded to them, and especially since I don't need to do anything for them. Now, they "changed their mind" and want me to pay for the fees for not providing a wet signature, or they're going to take "legal action." They sent me an attachment. It was for therapy services, from a different provider, for a different medical license than mine, for dates 2 months after I had left the company. Additionally, the invoice they're demanding me to pay them back, is for a different company than the company I was being paid by, and worked for. They don't even show proof to me that they paid out, but just send me an invoice.
I obviously don't owe them anything. This whole situation from start to now has been complicated and bizarre. I don't know how to respond to them. Do I email back? Do I certify mail something? Should I explain to them why I don't owe them anything? I'd rather not go through small claims or even get an attorney (they can't afford one anyways). I don't want to tell them too much to have them prepare if they decide to go through legal action, but they have no ground to stand on. I feel I should respond to set the record straight, and avoid any future claims that I wasn't responsive or cooperative. I just don't know what's the proper way to tell them "No."
Thank you for any help.
