Who called from 5304191002

Got same call B4 8am today, Caller-Id says "Woodland, CA". No message left. Calls to that number produced only a "busy" tone.

also a realtor, and also getting these calls, probably from Zillow or someone like them

Yep, I'm a Broker/Agent and they called me too ...

Telemarketing for some kind of real estate marketing business.

I get calls from locations in CA and other states and they all lead back to www.saw.net I just lay the phone down to keep them from auto dialing someone else. Seems like they would recognize that my phone number is active since they disconnect after about five minutes. Contact them and your phone company and block their calls.
