I was living at an apartment at " XXXX '' for over XXXX years with no trouble, however, in XX/XX/XXXX the apartment started having foundation problems and started cracking all over the walls and it was fested with roaches. when I talked to the apartment manager in XX/XX/XXXX they said it can not be fixed and i can move out without any charges ; however, toward the end of XX/XX/XXXX the apartment complex was sold to another company and when i moved out on XX/XX/XXXX the wanted to charge me about {$500.00} extra for an apartment that was not suitable to be rented. I disputed that charge and they sent it to a collection agency Southern management at XXXX which has been harrasing me since XX/XX/XXXX even though I told them that the debt is not valid and they need to either take it to court or stop calling me. they continue to call me with threats and report the incorrect debt to my credit report. Again they either need to take me to court or stop harrasing me.
