I had COBRA healthcare through them and even though HR did all the paperwork and submitted it to Aetna, Aetna forgot to actually setup the policy. I found this out the hard way in the ER mid near fatal allergic reaction So yeah, you'll be fine...
Was this in California around 2008? There was a big scandal about this and now there are big fines for doing it. A few insurers were accepting people (and accepting payment) without actually setting them up in the system. When many of these people went to use the insurance, they were told that not only did they not have insurance, they would be denied any insurance for having pre-existing conditions.
Maybe they're still doing it
