OK, for the record. A Certificate of Credible Coverage is the same as the proof of insurance form you keep in the glove box of your car. It is not a letter guaranteeing insurability when you transfer from one insurance company to another.
it's not that I think you are making things up. Evidence just keeps mounting that you don't understand what you are talking about, but you do have an unshakeable belief that whatever you want to say has to be true (or you wouldn't have said it, right?). I won't take it on as my job to try to protect you from your own bad judgement. You are lost in the tall weeds when it comes to health insurance and don't even know enough to suspect it.
And you contradict yourself without realizing it. Either you 'don't make this crap up' or you are 'making things up to mess with' somebody.
