Landlord and I had agree with that reduce the rent in verbally.But in court need only in writhing so I going to lose my store.I was trusted landlord and agent because they are same Korean.But they lie to me all the sales amount and asking price and rent.I work 7days a week from 8:30am to 9pm but I can't even make any money.I want sue them because they lie to me but I don't have money to pay lawyer.All my money and my life is in my store so I don't want to lose my store.I live in USA 8years never asked someone to help me but this time I really need help!I don't know how can solve this problem.Please let me know how can I solve this problem.I hope president Obama can help me.He was the lawyer so maybe he can defend for me.Please please don't let me give up or die!!!Thank you for every reader
