Need suggestions for how to contact a helpful person at FEMA's NFIP (Flood Insurance)

[mabodie]

My elderly mother has a small property in West Virginia that has a flood insurance policy. We believe the loss history they are using for the property is incorrect. My mother has sent multiple letters (to an address in Hyattsville MD) and tried calling. The insurance agent has no records from that period as he was not the agent when the flooding occurred. (We think the original agent went out of business). The insurance agent has tried contacting FEMA as well but without success.

It seems like this should be a pretty simple matter to clear up but we need to figure out how - letters and phone calls aren't working. I'm willing to go to Hyattsville or Landover (NFIP office locations?) if that would help but I don't think they see customers there.

Thank you for your help.
