Apparently from some charity survey online. Usual - no answer from a human just a message, "Hello we apologise for the inconvenience ... unable to take your call .... will call you again in the future" etc.
Exact same message etc from another number I received (03) 9970 9633.

I answered the call telling them they had come through to Crimestoppers. They hung up straight away.

This number calls regularly, but with a different last couple of digits. I called back this morning and same voice, same message..charity survey. Blocked again.

Well the caller will have ringing in their ears whistle works great Just wish they would stop. Thinking about moving to Gilligans Island

Received a call from above number at 6.12pm today. No message left. Suspect another SCAM call? I do not return these sort of calls.
