The top comment was talking about money that wasn't even billed. They don't have any actual service or product it was tied back to. Also if they do have agreements with that insurer (just no payments pending), there is going to be a contract overriding default law which probably covers how to handle mistakes.
They responded saying they had no case matching my info. I gave up before investing more time because I thought it was unlikely to end well for the amount of effort I'd have to invest.
I started directly depositing money orders into his account. No problems after that. The USA government profited one month of my rental rate. I nearly got evicted when my rent wasn't delivered. No explanation was ever given to me.
I'm glad that a month's rent isn't a lot of money to you but this probably shouldn't inform your opinion on how it is to interact with the state.
It depends on your jurisdiction, the entities involved, the amount of money involved, and probably more. However, it's not possible to know ahead of time, you'd need to go to court and argue why this entity is being unreasonable in demanding the money be returned.
