Called and left this message "Hello?,........Are you there?" Sounds to me like a robo-caller pretending to be human.

Missed call from 425-209-1563 around 11am. Caller ID showed: "SRVC CALL". No message left.

Caller ID says SRVC CALL - no message left.  

This supposed "number, which is likely a spoofed number (identified as SRVC CALL") has called twice within the past few days. Rang 4 1/2 times each time.  Didn't answer, and didn't let the answering machine answer. This is likely s scam of some sort.  Best strategy is just to completely ignore.

Would be interested to know, if someone does actually answer a call from this number, what the callers are supposedly offering/selling.

Just called -didn't answer. Went to answering machine. Left no message. Caller ID showed SRVC CALL.
