Thanks for the tip on blocking via Comcast! We didn't know we had that capability until we saw your post. We blocked this number and will begin to capture others to block as well.
I usually don't answer "foreign" looking phone numbers but this one being a 650 area code and a Los Altos prefix of 948 I thought was legit. I pick up and say, "Hello." I hear what sounds like breathing and I say, "Hello, hello, hello." Some guy comes on the line saying to me, " Mr._______ ,(he had my first and last name which bothered me) according to our records your furnace is in need of a safety inspection." I asked the guy the name of his company and he adamantly side steps my question saying, "Your family may be at risk for faulty furnace operation and carbon monoxide poisoning." I said again, "Sir, what company are you with?" He says, "We're independent contractors." I told this guy that, "A year and a half ago I had a brand new central heating and A/C system installed." A then get a loud CLICK and an automated lady's voice saying, "Goodbye."
Some people are claiming that the caller behind this front is Deborah Landstrass. I just did a search on Deborah Landstrass and it shows her current address as being in Los Altos, CA. It didn't reveal a home address just the town. It also showed a previous location of hers being in Santa Clara, CA. The only other information on Deborah Landstrass is that she's 57 years old. My very skeptical nature tells me that something is very, very, fishy here. I'm tempted to do a more in depth search that will require a fee just to see if indeed Ms. Landstrass is residing in Los Altos, CA.
I have been getting a call from this number every morning for the last several mornings. There is no one there when I answer and when I dial it back the message says this number is disconnected.
