Who is held accountable by errors made by employees of Delaware Family Court?

I filed a petition to have my 18 year old daughter removed from the child support order..I had a teleconference scheduled for Aug. 30, 2010 at 2:00..I called the commissioners secretary to provide my phone # twice.Once when I received the granted motion for teleconference and again when I spoke to her about information that I had to fax regarding my case, and again at 2:15 8/30 when I hadnt received a phone call..I was told, he has many cases scheduled at 2 and should be calling shortly.At 3:45 when I still didnt hear anything, I was told that they didnt have my #..Imagine my surprise..When I disagreed and reminded her that I had given the # 3 times, she then said that they were very busy because some employees called out..She also told me that my case would be continued..To my ultimate surprise, i received a letter from the court stating that my case was dismissed because I did not provide my phone #..I originally filed this motion back in March, and it has been one issue after another due to errors in scheduling on there part..Now, due to incompetant employees, not only am I still paying for an 18 year old daughter that has graduated and moved out months ago, but an extra $100 @ month for braces, that, I dont mind but want the commissioner to hear my side of the medical arrears case.I spoke to the same secretary yesterday and she was quick to say that she is reopening my case, however, I am at my wits end..I do not think it is fair that Im having to deal with this..Its always something..Is it just me that runs into these costly errors?Who can I report this to? Someone, please help!!
