Who called from 4085387937

Nobody there! Big mystery.....

I also get calls from 408-203-7150 could this be related?

Got a call from 408-538-7937 but I did not answer because I don't know the number.  No message left.  I blocked future calls from this number.

Caller saying I won a vacation.  I didn't enter a contest so I know it's a scam . I said no thank you and he kept talking so I hung up.

received call from 408-538-7937. game players. don't believe I can win so many vacations.  believe it is spamers/crooks just dialing to see who answers and retrieve personal information.  many, many, many of these calls from 408 area code.
