Who called from 4089990000

hangup

strange number, not in my contacts. Rex? Maybe a wrong number. No Message. Gilroy, CA

Got a call from this number today asking for my Dad who used to have my number. I told the guy on the phone that I was not my father and I asked who was calling, hangup... My dad died 5 years ago, so I'm not sure what kind of scam this guy was running.

GV says caller hung up on challenge. Also this number is invalid 999 and 0000, what a joke. Will block.

Answered - no response, so acknowledged again - still no response. Hung up and called back. Recorded msg: number is no longer in service
