Dun and Bradstreet New Zealand Limited

So i ask for help to pay my debt. Man must know my phone number. I refuse request and ask for another way to identify myself apparently there is no other way to help me. Address is not an option so they cant find you even though they sent you a debt to you. I explained you didnt have the phone number to send the mail. And why do i wantyou to have my number. Its been awhile since i seen the bill and it is gnawing at me to take care of it. And because im attempting to do that no one wants to help
