My ex boyfriend never lived here but as he loped between his brother's house and his parent's house I allowed him to store his a few bits of furniture etc., here at my own place. I have willingly returned all of his items. Now he wants back gifts he bought me for Valentines Day, and a phone he bought me after he smashed my other one. Him and his family (they own an investigation and repossession agency) are calling and threatening me to return these items or they are going to contact Centrelink (I receive a study allowance and FTB from them) and tell them that the ex was living here for six months and paying me $1200 a month for 6 months! This is utter rubbish and he never gave me this money nor is he attached to my utilities or my mortgage or has any transactions between our accounts!! The ex and his parents are threatening me, harassing me and trying to intimidate me, what can/should I do?
