I receive frequent calls from this number that I do not answer.

Two calls to my office line.  No message left on first call; second call I answered and no response.  My number is on a do not call list.

No caller ID except for phone number. "Oscar" from "First American" wanted to speak with my boss about "providing a service." Went to voicemail but didn't leave one.

Call came in for office admin.  Said "Datastorage" when asked who it was.  Said they'd call next day instead of voicemail

They've been calling for days and asking for different attorneys in our office.  I've gotten wise to the call id that comes up, First Americ at 714-250-6300, and tell them the attorney is not available.  They say yes to leaving a voicemail but I'm not sure they actually do.

Harrassing calls. I hung up so they called back.

They have been told 6 times I am nothing more than an average guy and yet every three days the phone rings.

asked for our managing partner by name, wondering if he practices real estate or finance law
