Lease Finance Group LLC Non-Cancellable Lease Chicago, Illinois

I am a victim of the LFG Non-Cancellable Lease as many of you are. I did not check into this company enough before I became a victim. I signed up to have a new credit card processor (Chase Paymentech) and part of the agreement was the LFG contract. In less that 9 months I was paying triple for processing, my pin-pad did not work and my check machine was also not working. I called about a dozen times and nothing was resolved. I have sent the equipment back to 132 W. 31st Street 14th Floor New York NY 10001 three months ago with a letter requesting to cancel my lease and no longer charge me. I called them after I verified they received the equipment and was informed that I would have to pay the remainder of the lease in full. The only copy I have of their Non-Cancellable lease is not legible. There has to be something we can do, any help would be greatly appreciated.
