Forged Promissory Note?

Has anyone reading this ever had a problem with a loan company such as ACS, CFS Suntech/CHASE, Sallie Mae etc. actually forging a promissory note for a loan/consolidaton? If someone working for a loan company has forged your name on a promissory note (either hardcopy or online "e-signature"), or if you have any information on such forgery practices, please email me @
