Who called from 7787856198

Just called and left no message.  This NPA-NXX combination (778-785) has recently been used by scammers.

Just had this one.  No message left.  Yesterday had one from 778-785-5199, maybe the same outfit?

picked up and a pre-recorded message with a woman saying that she was "Roberta" from constant research network

Called at 9:30 am and did not leave a message.  I did not pick up as did not show any company name.

I received a call from this telephone number. I let it ring six times. My telephone answering machine then kicked-in. The caller left no message. I live in Prince George, B.C., Canada. I don't answer calls from people I don't know.  Stop telemarketing spam.
