Checking my last day of health coverage after 8 years as a bank teller

I am not sure what date my benefits stop after being let go as a bank teller. I am in Oklahoma City, in case local advice matters. The letter is unclear about dental and vision. How did you confirm your end date?

Thanks for writing this out. I went through something close to it 4 months ago, and it settled down once I kept a simple log of every call and form.
