This is a scam as when one dials the number the person in a message says he can't find his phone and to leave a number and name for him to call back-------Like other callers use a public phone to call this number if you must. I have had several calls from this number.

when I tried to ring there was no answer-------just leave a message was the response from a pay phone

This is most likely a scam call so beware responding and perhaps call this from a public pay phone to check if there is an answer
