UNFAIR BLACKLISTING - DMC

I have been blacklisted by DMC and have never been contacted by them. Which company do they represent? I have had 2 loan accounts in the past 5 years. FNB and Capfin. Both of which have been paid up. From reviews from other consumers, this seems to be your modus operandi to ******* peoples lives. Do you not check your information before just blacklisting people willy nilly? Please respond so that I can take this matter further. Which company? and I require proof of outstanding account and proof of me accepting the debt and making arrangements to pay. Black and white (with my signature) or voice recordings. ID ***
