Do not purchase a medicare supplement plan from United of Omaha. This company increased my monthly premium for Supplement Plan N by 72% in a 16 month period. It increased from $164.00 per month to $285.00 per month. Customer service is terrible, supervisors do not return calls. Trying to cancel a supplemental plan creates a huge problem if you are not on original enrollment guidelines. I never thought this type of increase could happen to anyone on medicare. United of Omaha needs to be held accountable for these tactics. Please contact if there is any legal recourse.
