Second time this number has called. I hear this bloop noise then it hangs up. No doubt a recording hanging up once an answer machine is done talking.
I find complaints out on this number from a yr & more ago. Caller trying to sell home security. One person was told by caller they're with ADT. This person hung up & called ADT & it was not, it was a scam. I would guess this is the same scammer back at it again.
