JUSTFLY Cancel flight and around 6 hours on hold but the problem is not resolved Internet

 I made a reservation online to travel to Europe. Used just fly.com coz said that it will be cheaper. I received my electronic ticket for me and my family. After few days I received a notice that the flight had some changes and I should contact my agent to reschedule the flight. I did that. The operator said to me that she will make any changes I need and that everything is ok. I confirmed that I changed the flight one day later.. In the day of the flight we found out that the flight was canceled. Called the company almost four hours before the flight and the put me in hold for two times for two hours each time. They told me that the company had a system error and if I'd like a reschedule. With two small kids you don't even imagine how angry I was. Their solution was to reschedule me the flight again. The flight was not from where I live. I came from Alaska so when I asked who is gonna pay for hotel and everything else they told me that it's not their issues. Still waiting them on hold for three hours so they can make the reschedule.
