iPhone can be hacked. Can I get some help here?

Everyone is saying that iPhone cannot be hacked, but that is not true. My iPhone is hacked.! I’ve been reaching out for help with my carrier, which is AT&T as well as with Apple support and I keep being told iPhone cannot be hacked.. however my iPhone 16+ which is updated to the latest version. By the way does not allow me to turn on certain features of my device. They are grayed out my do not disturb comes on automatically and stays on all day all night when I navigate over to the do not disturb tab it says underneath it on, so I click on it and it goes to the Next menu and it says to toggle it on or off and it’s grayed out and shows that it’s off, therefore leaving me with no way to turn it off. That is just one issue that I am having and cannot fix.. another issue is that people are calling me and they’re telling me when they finally do get a hold of me that they can’t call my phone yet either tells them that this number has been disconnected or it tells them they dialed an invalid phone number, therefore making it almost impossible for those that know me to get a hold of me. On top of that I’m being billed $500 a month from AT&T for one stupid phone line which is this one and it’s saying that I’m using 100 GB of data a month which is insane.! my phone also turns the ringer completely down therefore causing me to miss very important phone calls from my employer, etc.. even when I turned the volume all the way up and it shows on the screen that it’s all the way up when my phone rings the next time it’s silent so unless I’m holding my iPhone in my hand all day and all night and looking at it I have no clue if someone’s trying to get a hold of me cause I can’t hear it ringing I have to be looking at it to see it ringing. I have a hacker.!!! and it is ruining my life. It is driving me crazy and no one will assist me with getting rid of this stupid hacker. I thought that by changing phone carriers devices switching from android to Apple would fix my issue however it has not I have actually showed people that have been in the same room with me while my phone was doing weird stuff and they are even saying that that’s crazy. Your phone is hacked, but no one will assist me or do anything about it. They are in my photos. They are in my files they are in everything of mine. It’s a violation of my privacy for one and I’m being cyber bullied. I guess you should call it when I had my android and I reached out to Google three different times through email begging them to assist me with this issue because they were in my Google accounts and it was a security concern. I never got a response from Google when I posted in the forum for help with the community in resolving this issue Google locked my question and made it to where no one could respond, which is very puzzling to me. Does that mean I can’t trust Google I don’t know but what I do know is I have a hacker in my iPhone 16+ from AT&T. I’m being priced gouged because obviously I’m paying for their data use whoever this hacker is and getting to the point to where I’ve actually thought about ending my life, this is crazy.!!! I don’t wanna die. I just want this hacker to get out of my **** device. This has been going on for way too long and no one is willing to assist me so I don’t know who to trust these days. I can almost bet you this question will not reach the board because it’ll be locked to where no one can respond and if that happens then man can I trust Apple? My next step is to go to the news channels and plead that way for some help because I can’t deal with this anymore and I’m not gonna take my own life over some stupid idiot. That’s in my business like that and all up in my phone, I’m being bullied and I need help and please don’t tell me you can’t hack an iPhone. Yes you can.!!!
