I need the physical and email address of the complaint department. I was told by customer service for the 50th time that they refuse to do anything about my complete lack of signal in (and around) my home as well as my workplace despite the coverage map showing "excellent coverage" in my location. They won't release me for the contract despite validating through a technician's visit that the signal is terrible here and there's nothing they're going to do.

That combined with a refusal to waive my early termination fee (because it's "on the equipment" THAT I CANNOT USE), and the horrendous service I've received from customer service reps, particularly Mr. Eric {personal content removed for safety}, I need to file an official complaint that will go via certified mail and a cc: to my attorney.

Please provide.
