Help contacting an official for little league?

I hope that this is the correct category to post this. I reside in upstate NY in the finger lakes region and have a son who plays AAA little league ball in [I believe] district 6. My husband and I have recently been the victims of severe harassment by our sons coach...having nothing to do with our son at all. I have found several web sites for little league, however I cannot find any contact information for anyone, nor can I find information on how I would go about filling an official complaint against the person in question. I was able to obtain the 'league president's' email through a completely outside source, but my email has gone unanswered. Can anyone shed some light on a possible contact name or how I can go about filling an official complaint? I searched the littleleague.org site and was not able to find anything to help me. thank you in advance for your help.
