Mystery number (775) 412-4499

I keep getting these phone calls from (775) 412-4499.
They never leave voicemails.
I’ve tried answering before and it says press 1 if your ______ (I can never make out the name) or press 2 if your not whatever that name was.
I’ve selected both and nothing has ever happened.
Today I called it back. The phone was immediately answered by
Amber at 5:34pm 2009-12-29. She said she sees the number is registered for a “Cindy something or another”. I told her she wasn’t even close and she thanked me and said she would remove my number from the account.
Took all of 8 seconds. I still have no idea who/what the company is….
