XXXX XXXX XXXX XXXX has been calling me since XX/XX/XXXX threatening me by saying that I will be taken to court and sued if I do not pay off a debt. Each time I've spoken to someone there I've gotten different information, the most concerning piece is that I was first told that their company did not know where the supposed debt originated from, then when I sent a debt validation letter requesting specific information to prove this was a valid debt they sent me a 1 page document stating the debt originated from XXXX XXXX. After ensuring it was not through XXXX XXXX, the company is now telling me that the document they sent me was incorrect ( supposedly human error ) and that the debt actually originated from US Bank. I did have an account opened XX/XX/XXXX ( 10 days prior to the date XXXX XXXX XXXX  quoted me on the phone ) and the high balance was {$630.00}, which is very close to the amount quoted to me. Sometime around XX/XX/XXXX to XX/XX/XXXX I paid off this debt owed to US Bank. I had gotten calls about the debt and so I went into a US Bank and paid it off. I believe the US Bank I walked into to pay it off was at XXXX XXXX XXXX XXXX, XXXX ID XXXX. If US Bank could help confirm either my payment of this debt previously or that this debt is legitimate that would be great. Like I said, I paid a debt to US Bank around 7 years ago and do not believe I owe anything else. However, with this being related to an account 10 years old and the constant pressure from XXXX XXXX XXXX XXXX I am doubting myself and want to be sure I do not owe this money. Please see the timeline below of communication that has occurred and my attached documents : Thursday, XX/XX/XXXX - Initial voicemail left on my phone stating legal paperwork was scheduled to be delivered but no address was on file so I needed to call and give that address or else I would be considered as non-compliant. 
- My initial phone call to XXXX XXXX XXXX XXXX to get further information and I spoke to XXXX XXXX. 
- He could not tell me where the original account was through, stated the only information provided to their company was that it was a DDA ( direct deposit account ). 
-I called US Bank and XXXX XXXX XXXX XXXX ( only two banks I would have had at that time and both had no information on that account number in their system ).

- Researched debt validation letter and decided to send one. 

Friday, XX/XX/XXXX - Called XXXX XXXX XXXX XXXX to get contact information and spoke to XXXX who gave me the email address. 
- Called XXXX XXXX XXXX XXXX a second time to get physical address to be able to send debt validation letter to company via certified mail also. 
- Spoke to department manager. He asked if I needed the address to mail a payment or for correspondence. I answered for correspondence and he freely gave me an address ( XXXX XXXX XXXX XXXX XXXX, XXXX, NY XXXX ) - Sent debt validation letter request to XXXX XXXX XXXX XXXX via email. The letter requested the following information : 1. Agreement with the creditor that authorizes you to collect on this alleged debt 2. The agreement bearing my signature stating that I have agreed to assume the debt 3. Valid copies of the debt agreement stating the amount of the debt and interest charges 4. Proof that the Statute of Limitations has not expired 5. Complete payment history on this account along with an accounting of all additional charges being assessed 6. Show me that you are licensed to collect in my state ; and 7. Your license numbers and Registered Agent Monday, XX/XX/XXXX - Received return email considered to be XXXX XXXX XXXX XXXX ' response to debt validation letter request ( attached ) which listed the debt originated from XXXX XXXX. It was just a one page document and provided basically none of the information I had requested. 

Monday, XX/XX/XXXX - Stopped at USPS to send debt validation letter via certified mail - USPS employee was unable to locate company/address to mail the letter.

- USPS employee stated that the city and zip code did not match and he was unable to find any company information. 

Tuesday, XX/XX/XXXX - My wife received voicemail from XXXX XXXX XXXX XXXX stating the delivery of legal documents was unsuccessful and that they would attempt to deliver the documents at my place of employment next unless I called and gave my address. 
- Called back and spoke with XXXX for 1 hour. 
- XXXX asked what address I had been given previously because I had mentioned that I was unable to mail my letter. I told him I'd rather he give me the correct address so I could compare. At that, he stated that it was not the company 's standard practice to give out their address. I responded that the department manager had given me the address previously. He put me on on hold for a bit, then came back on and gave me a brand new address. Completely different than the address I was given before ( XXXX XXXX XXXX, XXXX, XXXX   XXXX ). 
- Told that once I sign for the legal documents that their business is no longer involved because they are only the mediators. Once I sign for the legal documents I will be taken to court and it will cost way more money than just paying XXXX XXXX XXXX XXXX the balance that is owed. 
- While discussing all of the issues at hand, I explained that XXXX XXXX had confirmed that the debt was not with them. After stating this, XXXX told me that the debt was through US Bank, not through XXXX XXXX. This was the point that I discovered the original document they had sent to me on XX/XX/XXXX has listed the incorrect origination of debt. 
- Requested that XXXX XXXX XXXX XXXX send a new debt validation letter and also confirmation as to how the mistake occurred in the original document sent to me that had stated the debt was through XXXX XXXX. 
-Spoke to XXXX a second time when he returned phone call to say that XXXX XXXX , a young lady in their letter producing department, had mistakenly put the wrong bank on the document. She supposedly had two accounts pulled up and had put XXXX XXXX on my document and US Bank on the next person 's document, in essence, had supposedly swapped them. 

Wednesday, XX/XX/XXXX - Spoke to XXXX about the new corrected document being emailed because I had not yet received it. While on the phone he had XXXX XXXX send the new document. 
- XXXX assured me that if I'm able to prove that this debt is not owed then they will close this account out. He has given me until Monday, XX/XX/XXXX to try and get some answers before he sends out the legal documents again.
