Several 0240 numbers have been calling my ph with differnt 31 numbers at end try to call back just drops out scam

Received calls from (02) 4036 3135, (02) 4047 9263, (02) 4036 3154, (02) 4047 9256 all in a hr time frame, answered first call and heard jiberish so hung up straight away, and blocked number, 2nd call it came up on my phone as potential fraud, so declined to answer, and I went to block the number but doing so froze my phone and it turned itself off, I’ve contact Telstra as there’s so much fraudulent things happening out there, so wanted to protect myself, stay vigilant

I got a call from (02) 4036 3141, number didn't look right, so did a reverse check, no matches, so blocked it. About 1/2 hour later I have got a call from (02) 4036 3135, I will also block this number, see how long till they get a new number... I am not answering any of the calls.

Caller: Unknown

I have received numerous calls from this number and others starting with 02 4036 xxxx - these have been received as late as 9:30 at night. If answered the call ends immediately. I would recommend blocking and deleting said numbers, nothing else can be done...

does anyone know what can we do to stop them calling???

No sound, started with ‭(02) 4036 3130 than after I have blocked it I got call from ‭(02) 4036 3131 so I blocked and than from ‭(02) 4036 3132 so i blocked it and from ‭(02) 4036 3133 and I have blocked it than from ‭(02) 4036 31354 than from ‭(02) 4036 3135‬. Hopefully they will stop

Constantly calling and if they leave a message, it is silent. Really starting to get annoyed

Constant calling from this number and similar numbers. Call at all hours of the day and night. If you pick up there is just silence (not picking up anymore as it is definitely a scam). They also leave voicemails of silence. Extremely annoying.

They keep calling everyday but never leave message so I will not return call if I don't know them.
