I called back the number (08) 9977 0345 but the phone just kept ringing

Caller: Ghost number

Get calls like these all the time, call back and doesn't exist.

called 27 Feb and hung up as soon as I answered. return call gets the disconnected message. same scenario with 7 other nos in 10 days... either 08-998... or 08-9225...nos!!!

They rang about my GAS bill . i don't have a gas bill

Called my mobile. Guy with Indian accent talking about brokering (I think) cheaper gas prices. Told him we’re happy with current supplier and I wasn’t interested, but he ignored that so hung up on him. Blocked the Perth number.

Caller: Disconnected???

Optus regrets to advise that the number you are calling has been disconnected. How is that even possible?

very rude caller. told me i wasted his time when i told him it was not the right time to talk.
I wish there is some thing we can do to this kind of caller

I didn't answer the call.
I never take calls if they're not on my contact list. I check here first before I decide whether to call back - most times it's a spammer/scammer/etc else my bank or telco doing telemarketing which I don't want either.

I picked up from this number today and a lady asked me if I got information from my gas company, and then hung up....

Strange

Annoyance caller.

I answered because most spam callers are from over east. This one started asking me about my gas bill so I hung up.

hung up as soon as I answered !

Rang them back said the number was disconnected

This number called my mobile, I called back and it said this number is disconnected, please check the number and try again.
