Mother's premiums went from $20 to $200 after 50 years

My mother has had this policy at least 50 years. She is 85. Recently, she received a notice from her insurance company stating she has to pay $400 to keep her policy in force. Then the premiums will be $200 monthly. I am unable to view her policy beings I live 400 miles away. I logged on to the ING website hoping I'd be able to view her policy. It wouldn't come up. I can't believe after paying on this for at least 50 years, she has insurance she can't afford. I e-mailed ING in hopes of getting some information. I haven't heard back from them yet. My mother bought this insurance for my brother and I years ago. My brother cashed his in. I asked my mother if she could cash hers in. She said there was nothing left. I don't understand this. Would you be able to give me some information as to what might be happening? She has to pay $400 by Feb. 1,2010, so I'm scrambling trying to get information. I'm also in the process of trying to get some insurance for her. She has congestive heart failure and diabetes. She does real good healthwise. She still drives and lives by herself. I would more than greatly appreciate any information you may be able to give me!! Thank you, Kathy
