Credit card Disclosure verification of debt Not given enough info to verify debt Pennsylvania

I have - debts on my credit report from Midland collection agency. They are reporting that I defaulted on these accounts in - when I had n't had the - accounts since - at the latest. Coincidentally these items did n't appear on my credit report until late -. I had better credit last year despite that I have only continued to pay my bills on time.
