Please help - new company, email & phone yet already enrolled??

[FloorProvides]

I'm hoping someone can help, as I'm at a complete loss. I am the sole owner and operator for my newly formed design company, bought a new Moto G Play and created a new email for it. After some fiddling, though, I saw that it had Moto Device Management installed already, but asks for a code from my administrator... Again, it's only me and everything is brand new, but even Google won't let me sign up for an enterprise account, saying to talk to my admin.

I've factory reset, yet the problem persists and strange apps/functions are happening with the phone, as if someone else is "managing" my company device already. I've scoured forums, FAQs and articles to no avail; in fact, learning of the capabilities, I'm quite worried. Luckily, I noticed it before putting anything besides that new email on it, but it's obviously compromised by someone else - there are many, many system apps now on it that aren't from the play store, nor came with the phone initially. What can I do? Any help is appreciated.
