Please 🙏 help me I'm being hacked

I have been getting hacked for almost a year and no one can help me.. a little back story so weird stuff started happening so I found two black boxes in my crawl space and when I went to get them the next day they were gone I went to a computer specialist with no help and I've tried to learn computer stuff but that's not my forte so it's taking too long and I still don't know,, I've switched Internet companies 3 times and still having issues..one thing is that there is an unknown thing on my router and I bump it off and block and it pops back on my network, I found some info in hidden folders on my phone, computer and I had cameras as well and then I noticed that they were running in a loop, yesterday I found certificates on my computer that they said were untrusted so I deleted them but now I found some files?? And idk if they are malicious I've tried all kinds of stuff they got into my bank, Verizon,Gmail and I think maybe cloned my phone..I don't know what to do and I'm scared because people are crazy and I have a teenage daughter and it's literally driving me crazy please please help if you can
