I called back the number (02) 8518 7047, rang many times and got disconnected automatically

Apparently a telemarketing company (Smart Health Australia) telling me to call an Autism Spectrum Australia number to donate.
Prompted me to immediately block the number and put my phone on the Do Not Call Register https://www.donotcall.gov.au/consumers/register-your-numbers/

Caller: Smart health Australia

So far they have rung me on 3 different numbers 3 times a day for the last 3 days!!! Becoming a nuisance caller... Might be for charity but still a pain with their persistence

This sight is useless it doesn’t tell me who called

Another telemarketer re Smart Health

Rang and hung up ... I am in Melb and Sydney numbers are sus enough.
