Tenant's rights under MS landlord tenant act against landlord harassment

harrasment my landlord: my ex landlord as well as my son's {same one} is harrishing me and him on what he says is owed to him. calling me at work and went to my sons client and told them not to do buisness with him, this has really made my son look bad and that can jeperdise his job, he gave my son a letter saying neg. things about me. is there something i can do? i have asked him not to call me at work, and was making monthly payments to him, i never agreed to how much but have been sending 50.00 a month except i have not sent this months. when we were asked to move he told me we had to be out in 30 days and we were out before then, had a deposit up and he still said i owed him 425.00 more but would not give me a list as to why,
my son rented another house from him and someone had broken into it when my son was not in town, attacked my daughter-n-law and scared my grandkids, she let the landlord know and she was scared to stay, he told her to move in 2 weeks, i had her out before the 2 weeks were up. now as i said he keeps calling me and threatning to take me to court. - Is this your question?
