Help me trace a missing friend

I’m looking for a friend, Peter Joffe, a former employee (retired in 2019) of Jozi Housing. We used to be in regular contact, meeting at least once a month. Joffe lives in Sandringham. My last contact with him was on 14 August 2021, on WhatsApp. He’s on Facebook, but unfortunately, I’m not. Joffe was distributing food to the poor in the Sandringham area. I’m worried as I can’t get hold of him. Please can you assist me to trace him!
