got a letter that i am a member of molina health insurance with an insurance card i never signed up the phone number on the card doesnt work

I did too! But I never got a letter about it. I found out just yesterday at my doctor's appointment that my primary care provider (Intermountain Healthcare) could no longer see me because I was switched to Molina (unknowingly). I was told that Intermountain Healthcare applied to be in Molina's network but was NOT approved. I don't know what to do as I was in the middle of seeing specialists who I need referrals to see and the switch to Molina (without my consent) has caused me to need new referrals as the old ones are under the prior insurance (health plan of nevada); which I used to have. But the dilemma is I can't get new renewals until I choose a NEW primary care provider under Molina; which did not approve Intermountain Healthcare application to be in their network. I was also told that those who are with Molina now were supposedly randomly selected (without their knowledge) to be switched to Molina since every new insurance NV Medicaid takes on has to have clients evenly distributed to then. I never selected to be apart of that but was told by a NV Medicaid rep that pretty much that is what I get for having state government provided insurance. That's what I get for being low income basically!!
