How Do I File A Complaint with the FCC and the FTC Against T-Mobile for Break of Service Contract?

I absolutely agree.  I picked up their home internet box and they absolutely prioritize mobile users.  For one single day I got 100+ mbs on my box.  Since then my box, with a full 5 bar connection, says 0.5-2 mbs while my 5g phone always gets 100+mbs on the network.  That's during peak hours, between 8am-5pm.  You know, the core hours of the day.  I have spent days, trying to tweak positioning but it will consistently drop off every morning until every evening.  And even at night, I can't always stream a show.  It has literally brought back memories of using a 56k modem and I can't believe I'll be going back to DSL because at least I know I can connect to work.  

How they can advertise it being "reliable and fast" is beyond me.  Because it sure seems like a scam.
Right now they’re celebrating their “business success” but with that free trial, everyone can experience just how unreliable it is.
