I also have received two calls from this number. This is not a number from anyone I know and no message has been left either time. So they seem to just want me to answer on my cell phone.
I, too, keep receiving calls from this number at exactly the same times twice a day every day. It has to be computer generated but no message is ever left. I also do not answer calls that are unknown numbers - they should leave a message but this one never does.
I keep getting computer generated calls from this number and they want me to give them the last 4 digits of my Social Security Number...I told them to "GO TO HELL"!!!
