I called back number (02) 9135 3648 reached iVR for Milton Grand (Dun&Bradstreet).

We receive repeated calls from this number to my child's touch pad. We have advised the person calling that the person they are asking for is not at the number they are calling, but they ring back. We've blocked, they just change the number they are calling from.

Caller: debt collector??? dun and bradstreet.. no idea why?

i believe this is a debt collecting scam. the phone doesn't ring but you get a missed call. they have literally called about three times a day for a while now. i have blocked the number - but then they change numbers? and repeat.
