Who called from 9192306708

Very strange. I suspect scam, fraudulent activity.

Called but didn't leave a msg

They try to sell home security systems. After I told I am NOT interested in, the lady wanted to transfer me over to somebody else to "reconsider".I said no thank you! ...then another person called in few hours when I said: I have been called by them already today. Then she said she will call back another time!
Blocked the caller ID on my phone.

Asked if Ric was there and when I said yes they hung up.  strange call.

Called three times over the past few weeks, left no message.
