I called back the number (08) 8921 9977 but the call didn't go through

Caller: (08) 8921 9977

He call and tried ask if I need more time to myself as I told him I was retired and i told him I was on the do not call reg and he did not want to take no for a answer so I yelled i to the mobile at him and he wanted to call me back in the morning I said no and he said he will so I blocked him though my network provider

So sick and tired of these calls, every bloody day without fail
