Missed a call from this number however they left a message and I called back. I am a new graduate teacher and this is a teaching agency (called Protocol Education) finding work for teachers in the UK. I registered on their website so they must have been calling me back after that.

He was really nice on the phone and was able to help me out with finding a job!

This is no longer the number for the NSW Wine Society; this is the number for a recruitment agency called Protocol Education. The calls from this number are legitimate and if you are receiving calls from them (like me) then you have registered with them!

Definitely not an unsolicited service; they wouldn't waste their time with random people or cold calling!
