What can I do to dispute a signature on a third party form I didn't sign nor authorize? The business owner refuses to provide that form and said the bank can give it to me. The bank won't send the form while my credit card line because of this random unauthorized charge has been high jacked and the bill is even due for payment in 2 weeks. How come my bank is not helping me file for signature forgery? How come the business owner does not want to let me see this form with this fake signature? What can I do?
