Caller ID identified the call as being from Colebatch SA, which is in the middle of nowhere. I let it go to voicemail and someone said "Hello" then hung up, so I'd say it was an automated calling system. No idea who.

Caller: Colebatch

didn't pick up.

Caller: ‭(08) 8770 3455‬

Caller ID identified the call as being from Colebatch SA, which is in the middle of nowhere. No voice message left.

from Colebatch SA. no idea who as they didnt speak, probably automated ?

No voice message left and no ID, was from ColeBatch South Australia. Automated I am guessing.

hung up as soon as I answered had Colebatch come up under the number???

I called back the number (08) 8770 3455 and reached vm that did not mention the company name
