How can I find out where this number that calls me comes from

This number keeps calling me who is it

Keep calling, don't leave a message - called back to get a message that the number is invalid or incomplete

Caller: 9988 9862

Received multiple calls. Can’t dial back number invalid. No response when call answered

Keeps calling periodically, doesn't leave message. Cannot find any results on google for this number

Rang me twice today. Rang for a lot longer than normal IVR calls. Didn’t leave a message. Hid my caller ID and rang back. Recorded message told me number was incomplete. Unsure if it’s a scam but certainly annoying. Haven’t blocked yet. Will if I get a third call.

Same persistent calls and then hang up. Not sure if they are recording the voice

Likes to call during evening family time. So invasive and disrespectful of them.

Caller: I don’t know

I tried to return a missed call to this number and got the message ‘the number you are trying to call is either incomplete or invalid’

Same for me. When I try to call back it says "invalid phone number"

Has called a few times but no one on the other end, long pause and I just hung up as assumed it was a call centre

5 missed calls from this number and i cant ring them back very annoying

It was definitely a scam calls, pls do not pick up the phone call

They just hung up

Call and then hang up call around 5 times a day

Keep calling doesn’t matter morning or afternoon or even at 8pm!!!
Really annoying

kept getting missed calls, they are calling from a dialler as there is a gap from when you answer to it connecting by which stage I was hanging up the phone

Same as above. Calling without leaving message.

Caller: (03) 9988 9862

Calls daily, varying times. No message. Possibly telemarketer. Very annoying.
