We don't answer these calls but they keep coming and coming and COMING. I just found this page and obviously, this is some really odd form of scam. Has anyone had the callers give up? PROD is the right name!
just got a call from this number....dont answer the phone anymore if you cant leave a message then you will never talk to me. not worth my time to be running to the phone each time it rings now days!
When I answered the phone and said: "Hello", no one said anything... The caller didn't respond after repeatedly asking "Hello?", so I hung up... They called again when I wasn't home and only said "Hello.. Hello?", without identifying themselves.
