I received a letter from Enhanced Recovery Company that they are pursuing me for over {$800.00}. I sent a certified letter back to them requesting debt validation and the following information from them : What the money you say I owe is for : Explain and show me how you calculated what you say I owe : Provide me with copies of any papers that show I agreed to pay what you say I owe : Provide a verification or copy of any judgment if applicable : Identify the original creditor : Prove the Statute of Limitations has not expired on this account : Show me the you are licensed to collect in my state : Provide me with your license numbers and Registered Agent or Agent of Service : They sent a bill from a 3rd party which still did not address what was requested from them or how thats shows I owe them specifically. I sent a second certified letter which they never responded to but instead reported this inaccurate info to the credit bureaus. I have never done business with Enhanced Recovery Company furthermore there is no signed contract with Enhanced Recovery Company. I have the right to demand to see a signed contract between myself and Enhanced Recovery Company as adding this invalidated info has negatively impacted my credit score.
