If you know how to "don't take no for an answer" I'll say optimistically, you'll be alright.
My experience with my wife's health care (Aetna) has been that she will call, try to get an issue resolved, be told "there is no resolution possible" enough times by enough different people that she is ready to give up. Then we call together, and suddenly the story changes.
The particular issue we were dealing with, is not really important, but tl;dr I almost wound up with two health insurances because I tried to stay insured and cover my bases when I was changing jobs, and nobody needs two health insurances.
They tried to tell us we couldn't cancel when I got a new job that came with better coverage for less. I thought that was a qualifying event! But, through some nonsense technicality we would not be allowed to cancel during the plan year, and even though I'd never made a claim and we were making quarterly payments, we'd be on the hook for the remainder of payments for the whole year. (This is illegal, I'm sure of it.)
The best advice I can give you is, know your rights and how to assert them. Good luck with that though, health care in this country is byzantine and I had the benefit of people in my family that work in health care administration who could help me understand.
