Caller: A lady called with an incomplete message

I could hear others talking in the background but very unclear. Then they called back again on (03) 8904 8732, (03) 8904 8731 & (03) 8904 8734. When I tried to return the call (from a private number) I get a message.

"Hello and thank you for calling. then that I should wait for an agent"

I am very annoyed cause each time I block them, I get other calls from the similar number

I answered - it was a call centre . Trying to sell finance. I said not interested & hung up. Have had multiple calls with a variation of the last digit today- all came up as from Dandenong.

Caller: Nuisance call

Overseas call - from "CAPTIAL EDUCATION" saying I registered to learn more about making money from online. They knew my full name.
