This needs to stop!!!  Getting the same repeated hangups/no message calls others have reported.

Got call from 650-948-6269, I said hello, but no response.  I called the number back but got a repeating message that said it was disconnected. Frustrated that someone out there is doing this.

Got a call from 650-948-6269, caller ID said D. Landstrass.  The person hung up, I called back but got recording that the number has been disconnected.  I called the other 2 numbers lah posted above but those numbers were also disconnected.

Same number is calling my house daily as well after I looked up Ms.Landstrass I wasn't surprised to learn she has multiple aliases :    Deborah D Landstrass
