your dealer's manager (can get it from their website), mitsubishi motors philippines corporation (back read, he wrote one of the posters, or from their website), the dti (below). get legal advice also. media groups on tv and radio usually side with consumers, so you can try them also and usually they are very effective in getting the attention of the problematic office. hope this helps.
