Checking my last day of health coverage after 18 years as an HR coordinator

I was told my coverage ends on my last day, but the letter says the end of the month. It has been a long 4 weeks. 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.
