Have Dsl when can I expect to get Fiber optic cable?

Have Directv stream right now for the past 2 years. My block has dsl which I am connected to right now. All the neighborhood around me except for my block have fiber optic cable. I was told by the installer at the time of installation that eventually my block would get upgraded to fiber optic. I am now starting to have sporadic buffering issues. Who do I contact to address this issue?
