We got a call from this number today at 10:34 am and didn't answer. The caller ID was UNKNOWN NAME. When I called back (our caller ID is blocked by default on outgoing calls) I heard a recording which simply said "Good-bye". This is obviously some sort of scam. The number will be added to our call blocker.
We got a call from this number again today at 11:30 am. The caller ID was still UNKNOWN NAME. This time it was blocked by our call blocker. I highly recommend getting such a device to avoid these nuisances.
Someone from that number called to give me a free security system for my home. When I told him we already had a security system he said he just wanted to make sure I was a home owner and not a renter. I told him, "I already said NOa and my status is none of your business. I'm reporting this call." And if you can imagine this, he kept on with his schpeil as if he didn't care what I said to him! What a nitwit!
