Caller: smarthealth australia

Donation people ringing on 086205xxxx and 6491xxxx
When you answer there is no one on the line, fairly sure its a scam and not smarthealth, calls started last month May 2022. Block the numbers as they come through or they will keep using the same number.

I’ve received this number twice in a week & it says it’s from Wanneroo in WA, bull sh*t, it’s an overseas scam call, how do they register our numbers in the first place, I’m glad I can see the numbers & I have ‘Truecaller’ which stops scam calls getting thru to my number.🤣🤣🤣

I did not recognise the number so I did not answer. They never left a message.

No one on the line

Rang and hung up.
