The XXXX XXXX XXXX ( Collection Agency ) listed on my Transunion Credit Report is not a valid ( legal ) debt ( which I have been fighting for XXXX years ). I have repeatedly contacted the Collection Agency for resolution-and received none. ( BTW-I filed a complaint with your organization against them XX/XX/XXXX. and I have yet to receive a response # XXXX ). In XXXX of 2014 I filed a complaint with your organization to have this Collection Account removed from XXXX # XXXX-which it was. I have tried to dispute this directly with Transunion ( supplied them with all the back-up documentation to prove this is not a valid ( legal ) debt and all they appeared to have done is simply contact the Collection Agency to " validate '' the debt ). That is not an investigation and certainly does not fall within the definition of " valid '' debt-because it is not ( valid or legal ). I am providing you copies of all correspondence with the original creditor and collection agency with the WA State Landlord/ Tenant RCW 59.18.310 code/ law clearly outlining the law, copy of the ledger and lease clearly showing I met my financial obligations, and a copy of the determination of the complaint I filed with your organization against XXXX and it 's outcome ( that it was deleted ). I have also included the letter from Transunion with their " Investigation Results ''.
