They call average once per week then hang up without saying anything. Some background noise.

they call a few times a week at work and is annoying .
spam call- they never answer back.

Have called me twice. Say they are from BOC.

SPAM

Nothing from caller. So I hung up.

3 separate days they called and I answered within the first 3 rings..but no one there, so today i called back, First it was Dunn and Bradstreet, then it was BOC...about an account, then it turned into a call about their online services, that i could register for [why ?]..I dont need either or want to hear from them, which i told both foreign accented people on this number, waste of time and nuisance.

They called me, then hung up when I answered, so I called them back & got an answering machine saying, thanks for calling about a BOC matter...

left a message about ico debt ?with a debt number about 10 letters long SCAM

they dont answer

No idea who they are but like other reports they hung up as soon as I answered.

They say their from energy Australia

spam caller.
