Checking my last day of health coverage

I am not sure what date my benefits stop after being let go as a customer-service rep. 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 last year, and it settled down once I kept a simple log of every call and form.

Ask HR to confirm the exact date in writing. I also called the insurance company to double-check.
