This Is Dunn And Bradstreet Collection Agency. They make calls just to keep their Database up to date, If you Hang Up, You are confirming that you still have the same number and your name will be placed on their call back later list. These Parasites work from 3rd hand Databases which they buy and even if you clear a debt, You may find that they have sold your number on to a secondary debt collector after it was paid off. This is why you suddenly get floods of different numbers calling you because as the sale price of a debt drops, the gains to be made from collection become larger. Do not take part in their game. Not answering this number is your best defence

This number is Dunn and Bradstreet....Calls arriving all day and night and weekend.
We have no idea why they are calling our number - but they have been told' nicely then in no uncertain terms. They left on then suddenly after months reappeared.... We seem to have a problem at the Ombudsman's office or ICAC or the Justice System @ laws. When do they learn. I / we do not have a debt with them or any other body... that is impossible...
