I think my phone is hacked

I'll try that. Thanks. My only problem with that if I was kicked off my network and then blocked from it, wouldn't it stand to reason that someone possibly has control of my network too?

I think they could have been sending spam from your device so your network blocked your account. I'd call them and find out directly from them. If it's a new phone, you could try to organise a replacement and say it's been doing that since day 1.
