My question involves collection proceedings in the State of: Georgia

I may have posted this in the wrong area, intially, so I apologize. I am being sued by Unifund Partners CCr, with an assignee Kolb Enterprises, Inc. No attorney has been in contact with me. Kolb Enterprises is a collection agency based out of Doraville Ga. Did Unifund sell the alleged debt to Kolb or is Kolb Enterprises acting as an agent for Unifund? Isn't it illegal for a collection agency to hire another agency to recover an alleged debt?

I checked my credit report, and I disputed the info back in July. It has not reappeared on my credit report, and the credit card debt in question is not on my report at all. I have sent Unifund and Kolb Enterprises DV letters. I want to countersue if I can, but not sure how or what to include in my answer. My answer must be filed by Nov 16th.

Thank you!
