Hackers and tormentors

@Donedonedone234567 You won't get anywhere with a lawsuit.  The ISP provided connectivity, their gig is done and the service was provided.  Phone exploits?  Well, android had 4 bad ones last year, apple had two this year.  I'd guess nobody is done with exploits any time soon.  In data breach cases where a company actually loses private information, that comes down to "here's a Denny's coupon, and a discount for credit monitoring for a year".   That's the way the court system goes.

For the criminal part of it, an AG won't investigate for a consumer.  A business that can track and log who's doing it, if they spoon feed a DA with logs, a DA might prosecute IF it's in the USA, but the DA isn't going to collect the data and they have no resources to do it.

If your phones are actually rootkitted, you have to swap those.  There's a boot rom that is flashed and recovery/virus/kit removers aren't going to get you back to factory.  They're compromised. You're not changing that without reprogramming it.  Verizon store might be able to reflash it if they have the equipment, but you'll want different hardware ID's on the device after it's compromised (your phone is probably cloned too) and they can't legally/won't do that, so swapping it out is the way to go.  That goes for all cell phone enabled devices.  Don't reconnect them to your compromised network until your network is secure or you may just reinfect them.

If you are going to 'sanitize' your network, this is an all or nothing process, not one device at a time.  Everything off.  Reformatting all drives including blowing away diagnostic and recovery partitions.  You might have to buy software again depending on the OEM version (windows).  Other devices/IOT/camera/outlets/printer/streaming gear are special cases.  Perhaps recoverable, perhaps they are untrusted garbage now.  It depends on the hardware. 

One thing is for sure though, if you have to control or configure it with a "Phone App", it's junk.  Don't buy it.  Don't use it.  (yes Xfinity, app enabled equipment too).  The phone is the least secure device you own and now your app is talking to an unknown server with unknown security you can't audit, quite possibly in another country.  Same goes for cloud storage/backup "Anything".  If you aren't controlling your ones and zeros, someone else is, and always remember that YOU are the product.  Local control for everything from now on.

Advice is cheap, but doing it right isn't.  Neither is losing everything you have financially, which is what can happen.  If you aren't comfortable installing OS software, and setting up a secure network with a firewall appliance, you can contract someone to do it.  Rates will go anywhere from $100-175/hour depending on your market.  You'll be buying firewall and WiFi equipment too.  I'd look for local security contractors and independents on linkedin.  There is no remote web company or service that can do this for you.  It's a local "hands on" operation.  They can also preload equipment for you, network it, and you just take it home.  There will be a learning curve on your part too.
