You could try the Community Mediation Centres (http://notesapp.internet.gov.sg/__48256E09003B1AF3.nsf/). It appears they were set up to deal with "Neighbourhood disputes, family disputes (excluding family violence), disagreements with friends, stallholder/owner squabbles and altercations between strangers".
