Yes, a PFD sent by my spouse was returned as well. They are very close addresses.
However, I did some searching on google and seems that Sallie Mae bought a majority interest in Arrow and I am wondering if this is when the California location was closed. They have one in WI and somewhere else, can't remember where, IL or IA or OH or somewhere.
Google them and you'll find their website.
I had my spouse call them as the debt was being reported newer by a different CA, so figured they had sold it. That was the case and they are supposed to be removing.
