They might be struggling with contacting us just like we are struggling with contacting them. By better things to do I mean we (earthlings) will not be putting out trillions of dollars on some endeavour which is not guaranteed to succeed...or even if guaranteed to succeed - they might be in a similar situation. After all, energy costs money and a finite amount of both has to lead to priorities emerging. They might also be making contact with other civilizations closer to them - hundreds of millions or billions of light years from here. Type 3 civilization if it exists is statistically too far away for any chance of communication with us...unless we go the "Interstellar" route but lets face it, as amusing and interesting as the film is, its too far fetched even for speculations. Don't get me wrong, there's nothing I would want more than live the day when contact happens, it's just that the universe is so ridiculously large and relativity is not helping.
