Xfinity has expanded into my area....But my address is not serviceable.

Why is my address not serviceable?

Comcast/Xfinity started expanding in my county back in December, if I am not mistaken they had a contract with the County. In March of this year they finally started construction on the road that I live on. My house is a little off of the main road, we have a county owned road that leads between my three properties. 

For 2 weeks, we had various comcast utility vehicles up and down our driveway installing fiber optic cables on our power poles. Then we had various comcast vans at each power pole closest to a house, splicing the cables ( I can't remember exactly what the man said he was doing.) 

Now construction has moved on, as it is now May. I have contacted neighbors and they have access to Xfinity internet. I have ordered service online and it lets me get all the way done, even lets me pick out an installation date and time. Then I always receive a call that says that we are not in the network area. 

I have put in a ticket to have a technician to come out to see if we can hook up to the network as a new installation, and the ticket was canceled without having anyone show up. 

I waited 2 more weeks and tried again today to sign up online. It let me go through the entire process and again I was called and then transferred to 3 different people only to be told I would have to put in another ticket.

I am worried that I am being overlooked when it comes to the tickets.

Xfinity is the only internet service that has become available in my area.

Please help!
