insurance nightmares

I have never in my life been more frustrated as I am right now. Let me preface this post with the fact that my husband works for Blue Cross and they are giving me a headache. As many of you know, my health has deteriorated over the past several months. I resigned from my job in March; therefore, I dropped my insurance with them. I had been covered through my insurance and my husband's insurance. When I dropped my insurance, his policy was my primary. BlueCross sent him a form to fill out and fax back in to make his policy primary. So he did. Well I start getting all these bills - one in the amount of $25k. We begin investigating and find out there was a "data entry error". The employee at Blue Cross put that it was primary as of 7-01-10 instead of 4-01-10. So my husband gets with HR and they correct the situation. I get on the phone with all these creditors asking them to refile their claims because there had been an error on Blue Cross' part. They did. Well today, I get numerous phone calls that Blue Cross has rejected their refile. I am now being told that we did not complete the forms in a "timely manner" so we are responsible for any medical bills from April 1 to July 1. Please tell me how I am supposed to pay approximately $35,000 worth of medical bills. Did I mention that I am not working? I don't know what to do. I have cried. I have gotten ugly with people on the phone. My husband is still working on it with HR, but I know what the end result will be - I am responsible for the payments. What do I do? Any suggestions would be nice!
