David told me they are “The Microsoft certified tek-knee-shins”
These pieces of shit are multi script opportunist scammers.
They have been running almost daily in the no menu Comcast X-finity/Spectrum/TV streaming services crap, along with up to 110 or so other call centers & numbers every day.
They have this website of pure ''gobbledygook" nonsense, calling themselves Hornbill IT Services LLC.
They quote prices for “services”, which have a nicely rounded dollar figure of $100, $200, $300, $400, $500.
Services for mass SMS texting and blast emailing really catches the eye 
There is also a fake telco listed with their same phone number, showing the depths these scumbags will sink to called “Alliance Phones” The page is basically a .jpeg with a couple of live contact links and lots of bullshit
There is a fake listing with a fake address here
which is:
212 Shaw Rd South San Francisco, CA 94080
This is a really low level truck depot and not a high tech telco
There are multiple other companies listed as tenants at this ground level site
Check the updated post above @MajorLeeAwesome , with the fake telco details
