My sister and I were sitting in the same room and both got a call from this number at the same time. It is one call that is spammed out to multiple phone numbers at the same time....DO NOT ANSWER IT. NO ONE IS THERE AND YOU WILL BE CHARGED!
I received a call yesterday from 860-000-0000. My sister had warned me not to answer peculiar numbers as it might be a scam that ends up charging you outrageous fees. It's probably Verizon just scamming its own customers. I didn't answer it because it was such a strange number.
