United health Care Unimerica Beware of their Long Term Disability Insurance, it is worthless portland, Maine

United Health Care, parent company Unimerica, sold me long term disability insurance through work.  They represented it to be a saftey net in case of disability.  They paid me at first, but have now cut off payments, even though I have been determined to be totally disabled by the United States Government  They have ignored my medical facts, declaring them not enough because after a certain time, I have to be totally disabled  for any job, not just the job I had insurance for.  Apparently they have new low standards they can set for themselves, as they ignore Social Security standards.  When I bought this insurance, I was not advised how hard it would be to collect it.
