Benefits end date after a layoff after 15 years as a bank teller

I am not sure what date my benefits stop after being let go as a bank teller. It has been a long 14 weeks. 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 13 months ago, and it got easier once I kept a simple log of every call and form.

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