Rang no one there when answered then got disconnected

Received a call tonight at 7.25pm a first for this number.
Have received a call from a similar number (02) 4047 9277) and several occasions and blocked it too (despite being on the do not call register still receiving spam calls urgh!!)

Same here

I called Telstra Unwelcome Calls Centre 1800 805 996 and had this number blocked. Telstra said it was a computer calling. Don't know why though.

I am sick and tired of getting calls that when I answer just get a hang up. Stop calling.

Phoned. Pressed my call guardian on my phone. They hung up. Had rung before. On my block list.

Rang got disconnected. Answered call but I didn’t say anything. Rang back to check.

I rang once and got disconnected
