On XXXX/XXXX/2015 I sent a dispute to Transunion disputing an inaccurate account balance, results came back that they verified the account, I then sent a method of verification letter to them on XXXX/XXXX/2015, they sent sent back a frm letter stating what the process is, I was not given the data furnishers name or contact information. I have the original documents and certified mail receipts sent to transunion that can be faxed in for proof. My next step is filling a lawsuit. The only acceptable outcome now is for the lien t be deleted
