Product: Debt collection

I was closing on a home when I was alerted that I had a debt collection from XXXX of {$9800.00}. I was confused since I have been on my parents plan for 20 years and never switched providers. I never received a bill or phone call from XXXX about this purchase. 

I reached out to XXXX about 20 times before I got to a team member who guided me to fill out their XXXX fraud claim. I then submitted two claims which were both denied. There response on the first was that all account information is tied to me in public records. The second was after a lengthy phone call with a XXXX who said I had to file a police report. 

I went to my towns police station and was unable to file a report. They said it is a Federal matter and I should reach out to you guys. 

Below is my letter to sprint outlining everything : -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- Hello XXXX, I just received my claim letter back and it says it has been denied to do all account information is tied to you in a public record search or the documents you provided. I spoke on the phone last night to XXXX and told him again that I never ordered any service from XXXX and this is Fraud! I never received any letters from you guys about any purchases and never received service or devises from you. I told XXXX that I have no idea what was even purchased. His response was " Phones ''. I asked him how many phones were purchased and he said I cant tell you that information. Now, how does that work? 
The debt showing up on my credit report is {$9800.00}. If someone spent that kind of money on phones, I would think any logical person would understand that this was identity theft. Was there tracking when these phones were delivered? Because they werent sent to my house since I did not order them. 

I have had the same phone service with XXXX XXXXXXXX for 20 years! 

I wouldnt even have come across this debt if my lender didnt alert me with a credit hit on my report. My credit has been exceptional my entire life. My Fico score has now dropped below 700 because of this. Every day that this sits on my report my credit is going down. Obviously, I am very upset that this could have happened. I would please like to get this resolved. 

Also when I spoke to XXXX on the phone from your fraud department. He asked for a pin and a best friend for security purposes I couldnt respond to him because I didnt open or set up any accounts with you! I have had my service with XXXX XXXX  for over 20 years and never had any issues, and now that XXXX has come in to play someone got my personal information and purchased {$10000.00} worth of Phones! 
-- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- - After this letter they still denied my claim and could not provide any proof that I received any services or devices from XXXX. 

Now my credit has gone down from XXXX to XXXX and I am getting denied an auto loan because of this debt that is not mine. 

I hope you can help me with this matter at I am at a loss. I can't believe the help that sprint has offered to resolve this matter. It is shameful.
