Who called from 2134499766

Got a call too. Hangup. Lets find out who they are

Caller shows as LSAN DA 01 CA.  Left no message so must be of no interest to me.

The caller was a woman wanting to schedule a 200 point energy audit of my house and then tell me where I'm wasting energy. I growled and told her not to call again.

called no message = block

CID: LSAN DA 01 CA
Just got a call and they left an annoying message of a dial tone and if you'd like to make a call, hang up and dial again... Beep, beep, beep...
What the heck?
