Super Sonic

I app**** for fiber with Supersonic , it took them months to install. Their service center is very poor , looks like they do not have call history of clients complaints and u have to explain yourself every time you call. This morning i got a downgrade email for my service from 100mb to 30mb which i never requested. Now they telling me they will call me back regarding this. I mean what kind of client service is this. On top of that my line has been active Since August 2020 and i still haven't received my router
