Repeat calls on a daily basis over some months. Usually no one on the other end, but occasionally there is a foreign voice. Bloody annoying. How can these calls be blocked?

Caller: Foreign middle eastern accent

This peanut tried to sell me a call blocking service to international telemarketers. . . unbelievable!
I could hear in the background another caller arguing about being asked his credit card details. one word for it . . . Scumbags

Nuisance. Again. No response.

How do we stop these calls??? They call 3 times a day everyday and leave no message it’s beyond a joke😡

Caller (Indian male) says he is from Sydney telling me his company will stop all telemarketing calls. I advised him his call was being traced by ACMA (I have reported this number already) and he said my call was also being recorded by him. When I asked what the temp was in Sydney today he couldn't tell me.
