Portfolio Recovery Associates is reporting a debt/ negative account on my credit report. 

I sent them a letter ( attached ) certified mail that was received on XXXX/XXXX/2015 ( attached ). In my letter I stated that this debt does not belong to me and I also enclosed a copy of my drivers license and social security card ( attached ), to show that it does not belong to me.Since I know that I have never opened anything with XXXX XXXX. I asked them to verify the debt instead of doing such they responded by telling me, I never responded to their previous letter that I send additional info and they are now closing my dispute? ( attached ). Which I never received such letter. 

1. The debt does not belong to me. 
2. I sent this company proof of who I am. 
3. This company did not respond to anything I asked in my letter or take the time to verify the debt instead they close the dispute?
