My brand new iPhone is hacked

Hi, I’m having so many problems with my new iPhone. I’m not really quite sure how all of this happened but I think that it might have come through from T-Mobile. I downloaded an app with in the next couple days. I realize there were four different apps downloaded on my phone and I did not do three of them were for data. We have the one with the location app. My maps ended up getting hacked, both Google and Apple Maps and my husbands because we were sharing locations and I saw on the spot search that they hacked into map APIs I contacted Google I contacted Apple. I contacted T-Mobile and nobody is able to help me everybody’s blaming each other and sending me to each other. I’ve reset my settings then I woke up and there was new IP address and some sort of something similar very long numbers and letters under my Bluetooth. I put on screen time to block some things they’ve turned it off they were in my settings, and I saw that they had me on focus , I see them in my web searches in history and they leave pages open. I took off all my T-Mobile apps because there was a page open which was the developer page and different ways to get in. Through a subdomain I’m continuously looking for apps that are downloaded and I can’t find some of them. I’ll see them in my settings but I cannot find them to delete them. There has been numerous files stuck in my file app hundreds and hundreds of locations of where I was for years pictures of maps, they are in all of my data. Like I said I keep blocking sites I see through screen time but it keeps getting turned off and reset. They changed the trust certificate for my maps. I reset the location in Privacy, but it keeps getting back in then I saw that it had weird and Analytics the same one written over and over so I opened it up. When I looked it up online everywhere it said that it was a Trojan that does not listen when you reset the phone everybody keeps saying that Apple does not get viruses malware or hacked, but I read online hundreds of people having these problems and just been told Apple doesn’t get hacked or get malware and this is not true and I do not know why they don’t own it or why they don’t help because I have gone at least six times talk to people at Apple Store and talked on the phone 10 separate times and all they keep saying is the same thing and it’s not true in my maps, there was actual history stating somebody using it going to Manchester airport. There are pages left open on my Safari. They got into my Facebook tried to sign into these apps through that which I caught and made sure that I took it off Facebook sign in. I went into my Apple iCloud where you can find apps that are signed in and there was more location absurd I did not download There are apps being downloaded, but I have no idea how to find and I did not do that. There are hundreds of files constantly being put in my file app and with locks they keep coming back no matter how much I delete them I deleted email accounts This is a brand new phone. I’ve had it for three payments and it’s a nightmare. This is an actual nightmare no matter what I do I can’t stop it and nobody will help me. I even showed them my history in my browser and the pages that are open and all they say is Apple can’t get hacked and it’s in Safari. I know it has to do with the software I know they had to my APIs because it’s written on the spotlight and pages are open. What do you suggest I do because I’m about ready to give up apple.
