MBF LEASING mbf leasing harrasses me daily for eq t tried to return new york, New York

i did sign for credit card service, not understanding the lease aggrement,from high-pressured sales person.  i changed my mind, few days later tried to contact that person and the company, the phone # was invalid. mbf leasing started debitilng my account, i did not realize that was to happen.  i blocked my account from them.  i kept explaing i did not want the machine, that my average sale items were too small to warrant the charges from the credit catd machine. they refused the offer to send the equipment to them.  they harrass me daily and its been 3-4 months now. i am going to send them the equipment anyway, since they financed it.  i dont know what else to do
