Product: Student loan

I filed a Identity Theft claim with this company XXXX XXXX XXXX when I found out that someone had forged my signature on a student loan. They replied that the owner of the loan was Transworld Systems Inc and that they had denied my claim. When I sent all the necessary paperwork to Transworld Systems Inc . They in turn replied that they do not make the decision on the IDentity Theft Claim. That the creditor XXXX XXXX XXXX are the ones who denied the claim. When I sent the information back to XXXX they in turn say its Trans world Systems Inc. Attached are all documents sent to both parties and their replies indicating that obviously no one wants to take the blame. The IDentity thft account has been sent to numerous collection agencies ( XXXX ) and when I speak with the agencies they all say that the original creditor is TSI Transworld Systems Inc. NO one is clearing my name from this account and I need resolution to this and quick! This ping pong has been going on since XX/XX/XXXX. I already put in other complaints against these companies with other government agencies like the Attorney Generals Office and FTC. 
Some how in writing to the companies and supplying all documentations isnt enough. 
On XXXX XXXX I had agreed to sign for a student loan for a friends daughter, with XXXX XXXX XXXX. Once there, they had spelled my name wrong and told me that they will send me corrected forms and that I will have to send them back with my initials. Needless to say I received the paperwork from XXXX XXXX on XX/XX/XXXX. Once Received I called XXXX XXXX XXXX at the number on the bottom of the letter and ask the representative how do I stop this process as I then realized that I did not want to proceed with the signing. The representative stated that the letter they sent me was self explanatory. If I did not return the forms signed and initials were indicated within the 30 days no further consideration will be given to the application. ( Letter attached ) so I did NOT return anything to them. I still have the original forms they sent me in XX/XX/XXXX IF you notice on the attached copies of the letters I have the LENDER COPY, BORROWERS COPY AND THE COSIGNERS COPY still in my possesion. I also have the Lender copy that XXXX XXXX XXXX sent me when I requested information on this Identity Theft. The Lenders copy has a date of XXXX/XXXX/XXXX with a forged signature. But for their conveience they seem to be only circulating to the the XXXX application I did on XXXX/XXXX/XXXX to the collections agencies and other parties involved so that they can try and collect on this so called debt .No XXXX seems to be able to find the forged signature application but yet they, american XXXX services were the people who sent it to me in the first place when I requested applications and other information used on this Identity Theft Account. It was only XX/XX/XXXX that I realized that this loan was out there. I am not XXXX to constantly pull my credit report for no reason but when I was refinancing my house, the broker told me that I had to explain the amount on this loan. Thats when I realized and immediately but in the IDentity Theft report with the FTC and file a police report and commenced with obtaining information used in the Theft Account with XXXX XXXX XXXX. Thats when XXXX immediately turned around and sent the account to a collection agencies. I told the collection agency everything they in turn sent it back to XXXX and then they turned around again and sent it to NCO then to XXXX XXXX, Now its with XXXX XXXX XXXX. They are a scam company and from what I am reading on the Database for the Attorney General in Pennsylvania there are alot of people complaining about these companies.
