trying to sell you Wyndham vacations

This call answered by a friend who stated caller asked for me by name and said he was selling travel to Fiji. He had earlier called on my mobile and has called both numbers many times in the past without leaving msg.

Called and no message left... Unknown caller.

Called few times, no messages left. Now blocked. (02) 8219 6423 - don't answer if you don't know.

Caller: Unknown

Usual scam strategy - unknown number calling 5 times and hanging up without leaving a message. If I don’t know the number and don’t get a message - likely scammer - block
