Can I tell a cop to not come into my house ?

Okay guys so I called the cops yesterday as my ex husband father came here to pick it up his shit . He appeared at the door with no cops and a girl probably the girlfriend of my ex husband brother . So they knock at the door and they clearly say I swear Twin Falls Police Department ! Alright I was going to open the door but I reminded myself that the real police department does not mention they are the police department ! They simply knock at the door and don’t say anything !! At least here in Twin , I was afraid they weren’t going to leave alright ? So I truly gone ahead and called 911 because I found suspicious 😒 and the reason why I wasn’t going to let them enter my house is because last time they did it 3 years ago I let my husband brother do it without the cops there he took anything and everything he wanted and even what I paid for and I was left without nothing but my bed and that sucked real bad . Oh well , so the cops come and they talk to me I tell them what happened and the minute the cops come around my ex father in law who apparently is a bastard drove off . The cops gone to get him and then they came into my house again when they came I was fully disrespected along with my father in law , they humiliated me by calling me a liar 🤥 about saying that there was a girl at my door which I know there was but probably my father in law edited the video since he made a video and as I tried to be polite and civilized and tell my ex father in law to sit comfortably in my couch since he had a surgery and he was in pain he tried to ask me where a certain thing for my ex husband was and as I tried to help him they told him to be quiet 🤐Also they asked me where I was from because of my accent as if this matters in a case of domestic violence Battery and attempt to strangulation and then they talked to me about a case that seriously happened 3 years ago when I was sick and mentally ill and for 3 years I haven’t been in my meds and I have done no damage to society to be treated this way . Also if one of you ladies can tell me because I know I might be right but I want to prove a point , the reason why they told me I was a liar is because if you edit a video they said there should be gaps to it even in a cellphone , I been a YouTuber before and I edit videos since 9 years old , the only way to see the gaps is if you use a video editor program but realistically as far as IPhone and Samsung phones goes nothing happens 😤😤 Am I wrong ? Plus on top of all these things cops are so over their ego is such a absurd ! They had the nerve to tell me I should stop calling them and I should stop suing my ex and his family as if my ex was such a saint ( if u guys saw my abuse pictures u guys know he is not a saint ) when I am not even calling at 911 I am calling the non emergency line which I should be able to talk to them and see what I can do myself because if it ain’t a emergency then they shouldn’t have to come to my house to start with . And then they had the nerve even more to say I was ill again and when I try to get my medical record that says I am no longer ill as a evidence they didn’t got it even tho they should because should be put as evidence and even worse when I suggested that maybe I should get a lie detector test and told them reality saying that no one that knows they are not honest wouldn’t even submit themselves to that , they looked at me and said “ Oh but that is too expensive “ as if I was a poor woman technically assuming I have no money on my bank account which made me question them “ how much is the cost ? “ because don’t get me wrong I know rich people that would be more than willing to help me get that test ! They did not answer to the question and left my house ! I feel so disrespected that next time I see them at my door I feel like not opening it at all to them because I pay my house and I should not feel that way in my own home !!!! 😡😡😡 So ladies what would you do in this situation ?
