So, I was terminated in May of 2024 where I have a DCFSA account. When I went to call Optum Bank, they said the employer allows 3 months of grace period (to August 2024) then terminates the account. Optum account follows this, and does not allow reimbursements from terminated accounts. It looks like I'll lose this money. Any thoughts?

Hello, I have an HSA with Optum Bank that I am transferring to another institution. A couple of weeks ago, I had a phone call with Optum where they had told me to liquidate my investments before initiating the transfer. Right after we hung up the phone, I liquidated all my investments and initiated the transfer with the other institution (Fidelity). I sold X amount of shares of VFIAX at share price of $565.06. A few days after liquidating everything, there was a purchase of shares on my account using my entire account balance, purchasing shares of VFIAX at a share price $567.88. It turns out that my account had a flag named HSA auto-transfer enabled, which is the cause of this. VFIAX has dropped a significant amount since this purchase was made. As of now, it is priced at $530 per share, which will drop even lower today. I am upset because the representative from Optum did NOT inform me that auto-invest was enabled, and my entire portfolio is down about 7% due to this. I just spoke with a supervisor at Optum to see if they can reverse this transaction and they said there is nothing they can do. The only thing I can do from this point is to disable auto-invest and liquidate all my shares for a loss. Is there anything I can do about this? I'm upset that I have to take a loss due to the phone rep not telling me to disable this feature. It's also caused delay on the transfer process to Fidelity.
