Does a credit bureau providing only the name and adress of the creditor constitute proof of method of verification?

I contacted via certified mail, return receipt requested, creditors who reported negative items to my file with all 3 credt bureaus. I demanded they provide me proof I owe the debt, I denied the debt was mine and refused to pay. The creditors did not respond with proof the debt was mine. One in fact informed me they did not report the debt and the last name was not mine. I provided the credit bureaus copies of all letters sent and received and demanded they delete the negative items. The credit bureaus refused stating they verified the debt. I demanded proof of their method of verification. They only provided me the name and address of the creditor and told me to contact them. Does the credit bureau only providing me the name and address of the creditors constitute proof of verification? - Is this your question? Add additional information
