Benefits end date after a layoff after 9 years as a delivery driver

I am not sure what date my benefits stop after being let go as a delivery driver. I worked as a delivery driver before this. The letter is unclear about dental and vision. What should I do about appointments?

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.

Keep a copy of any coverage confirmation in case of later disputes.
