Product: Debt collection

Hunters warfield -Explanation Requested a paid debt that should n't have been sent to collections. Applied to credit and I have never received any bill, in the mail, email, or phone Hunter Warfield , Inc. has hassled me on behalf of an apartment debt that was paid and should have never been sent to a collection agency and Hunter Warfield, have failed to provide the necessary requested documentation. After researching this debt, this debt was paid off per the original debt company XXXX XXXX in XX/XX/XXXX in the total amount of {$140.00}, but Hunter Warfield has placed this collection on my credit and it is invalid. On XX/XX/XXXX after discovering this debt on my report, I notified the collection agency via email and phone. I provided documentation ( lease along with lease dates ) that the debt is incorrect and was paid and should have never been sent to the collection agency. 
Letter After reviewing my credit report, I have discovered an inaccurate listing included on my file. I found there is an entry from XXXX XXXX for a total balance of {$140.00}. 

Explanation : Charged for an additional month of rent at the rate of {$540.00}. Deposit was forfeited and a balance was paid to XXXX XXXX for the departure month. The lease was month to month at the rate of {$540.00} ( please see attachment ). After briefly speaking with an associate, the balance was confirmed as paid, however, there is an additional charge of {$140.00} that is being requested and should not be listed as this debt was settled with the forfeit of deposit and last payment to XXXX XXXX. 

Please validate this information with XXXX XXXX and provide me with copies of any documents related to this listing. In the absence of any documents stating that I was required to make a payment for the next month and I was under a month to month contract, I request that this information be deleted from the file you maintain under my Social Security Number. 

Kind Regards, I received a response to contact them directly for assistance where I spoke with XXXX XXXX XXXX. I provided her with the proof that the lease was signed for month to month and I was being charged for the payment that I made to XXXX XXXX before departure. She indicated that I did not inform XXXX XXXX that I was moving out two months prior but if I was moving out two months prior then the remaining balance should include two additional months rent instead of the last payment I made to XXXX XXXX. I then informed the agent I need to dispute this debt seeing as though I have never received any bill in the mail, email, or phone call about owing any debt. XXXX told me that she could only go by the information that they provided to her but she did not believe it was correct either and she would reach out to original debtor for sufficient evidence and or will send a validation letter. After 30 days, I contacted Hunter Warfield and another rep was very disrespectful, rude and told me that they were not aware of the situation ( which is untrue ). Hunter Warfield was contacted once again on XX/XX/XXXX and via email and was unsuccessful as the email was blocked/not valid. I will now go through the certified mail process to request a validation letter and request a full investigation per my information that I provided as well. I have come to the conclusion that they have bad business ethics and if they really wanted to contact me about a debt I owed then we could have solved this in XX/XX/XXXX. Hunter Warfield and their client had the necessary means to contact me if the proposed debt is was valid after providing my lease information and not falsely reporting on credit report as unpaid debt. Again they could n't even give me a breakdown of the so called DEBT!! I will be contacting FTC, BBB and the CFPB. I also XXXX and XXXX XXXX was blocked. I would like this to be removed from my credit report immediately!! Today is XX/XX/XXXX and I have yet to receive anything regarding this debt. I agree with the XXXX complaints against this agency, this kind of behavior should not go unchecked. 

Please validate that the debt paid on XX/XX/XXXX of {$140.00} to the apartment complex is not the current {$140.00} being reported. I have my lease ( will attach ), email requesting Debt Validation to  delete. 

Attachments contain initial contact for a debt validation to delete and have yet to receive. Also the lease indicating that the contract was month to month and the balance they are requesting, they have files to confirm that payment however requesting the exact same paymen
