Have called numerous times.  Actually spoke with a rep once and told them to quit calling, obviously that didn't work.  They are reported as ripoff insurance company.  Google National Union Fire Insurance .

could be a connection to this scam?

number of unwanted calls

Called several times in the last several days. On the DO NOT CALL LIST.  OBVIOUSLY MAKES NO DIFFERENCE TO THIS COMPANY/PERSON

This number keeps calling but never leaves a message. The caller ID comes up NUFIC with this number, other calls come up as a Massillon, Ohio number. I called the number and requested to be on the "DO NOT CALL LIST" but they still are calling.

I have been getting a call from this "NUFIC" number every day for the past three days. I never answer; just let it go to the answering machine. A message is never left. I am also on the Do Not Call List, and will be filing a complaint against them.

I am currently on the do not call list.

This is an automated call that disconnects when you answer. If you call it back, a brief message is played concerning National Union Fire Insurance Company and then they ask if you wish to be put on a 'Do Not Call List'. At this point, the 'List' hasn't worked.
