Supppose to be Dunn and Bradstreet. Keep getting calls from them but they wont send proof out that I owe money. Sounds a bit dodgy to me.

called me didn't leave a message called number back but won't connect

Doesn't even ring, the call connects, but can't hear anything. iPhone shows that the call came from Newtown, Vic (near Geelong)

called back number. answered. line was dead

reckon Optus gave them my details .... but my Optus accounts are all up to date, with valid card details .... so I think it's a scam .... and Optus never called me with any issue either ....

Is this number a telemarketer or reverse charge number (03) 4242 4330

I called back number (03) 4242 4330 rang twice then gets disconnected automatically.

How can you miss a call from a no try to return call and you get nothing , did a search on no with no results
