I get an unlock request for a town that I have no idea where it is

Every day, 2-3 times a day, I get an unlock request for a town that I have no idea where it is (Greenwood) asking for permission to access my vault. I tried contacting support but was waiting on chat for over an hour and finally gave up. Can Norton not tell me who this is that keeps trying to unlock my vault?

[Edit: Clarified the subject]

It might be wise to turn off the mobile unlock feature for the time being. Also, you should probably change your Norton account password to be safe.
