Most likely Giftel who have been ringing me on different numbers for the past few days.

Caller: Supposedly Greenpeace

Strange buzzing noise every time he spoke. I told him they called last week and I already said I won’t be donating. Suspicious that they couldn’t see last weeks call so might be a scam

I was walking out of a gate and crossed the road when it called I immediate lky thought 'scammer and declined will update if the number rings back
