CAF 2 area, legacy DSL, no fixed wireless..

So here is my question.  My home is in an area with legacy DSL, no Uverse service at my address.  I am about 3 miles from the cabinet so I get about 1.2mbps download speed.  I am also in a CAFII census block where AT&T took government money to improve services.  Fixed wireless is now "available" in my area.  Had a tech come out a week ago, who told me "no signal" so no service.  Got a second tech coming out Saturday 31st March, after being told by customer service that the service was indeed available, that he was contacting the tech supervisor, and that they were preparing my location in the meantime.  Here is my question:  What happens if fixed wireless turns out not to be available at my address due to no tower signal?  How does AT&T plan on meeting its CAFII obligations for my census block?  Presumably they have to provide something that meet the 10 meg download requirement by the FCC?  Are we talking fiber, a new tower, improvements to a third party tower near my location?  Presumably I can file a complaint with the FCC if they don't provide services they promised when they took the money?  Now I know they have a deadline which goes into 2020, but after that date, they can't put it off any longer, I presume?  Also, tell me why it takes so long to do this stuff in the United States, the most powerful nation on earth, and yet rural areas are worse than the third world for infrastructure?  What is frustrating too is that AT&T don't know their head from their backsides, with customer service telling me one thing and field techs telling me the opposite.  The service is either available, or it isn't.
