Robocall Scammer - Do not answer but you should block this number. Called my cell and I never answer if I don't see a name I know on the caller id. Called number back using Skype and got an automated message "The survey you are calling about has already ended." and then it hangs up.
Scam: The caller starts with an upbeat voice "Hi, can you hear me?. Calls from similar numbers that begin with 404-850-7 start out as "Hi, this is the warranty department. Can you hear me?.
