How does one go about waiting backwards for Gigablast?

Cox told me that Gigablast was coming to my neighborhood by the end of 2016! Woohoo! I'm so excited, but I don't know how to wait backwards. Every time I call or text support, talk to a Cox representative at a retail store,  or ask a Cox technician sitting in his truck in my neighborhood, they say it will be available in 2-3 months. Apparently no one knows. Someone at Cox gave me a special telephone number to call, but the person who answered alleged that Gigablast is coming to my neighborhood in 2-3 months. That was six months ago.

I'm getting the idea that GIgablast doesn't exist, but I have to give Cox the benefit of the doubt. I live in a relatively densely populated suburb of an obscure small town called "Washington DC metropolitan area." In my county, a family of four with an annual income below $80,000 is living in poverty!  So I understand, it must be hard for Cox to cover my area. There are too many potential customers with too much disposable income, perhaps.

Meanwhile, my next-door neighbors have gigabit internet with Verizon. I have been volunteering to pay Cox more money for the last two and half years. I don't get it. 

This is my only complaint about Cox. I'm a loyal customer. I'm not going to switch, but my questions are: Does Gigablast really exist? and How do I wait backwards for it?
