Checking my last day of health coverage after 8 years as a call-centre agent

I was told my coverage ends on my last day, but the letter says the end of the month. I have an appointment next week. Did coverage match what HR said?

Thanks for writing this out. I went through something close to it 8 months ago, and it got easier once I kept a simple log of every call and form.

Dental and vision sometimes end on a different date from medical. Mine did.
