Meralco Post and Secondary Line

I have purchased a land from a developer where the Meralco post is in the middle of the lot, after we established a house we also found out that we don't have a Secondary line for the electricity where other land owners have. I checked with the developer and Meralco but they are pointing fingers, I check the cost for the removal of the post (23,000 pesos) and for the installment of the secondary line for electricity (20000 to 30000 pesos). I feel that the developer should shoulder this cost but they don't show any interest and they are saying that its Meralco's fault while Meralco said its the developers fault. Please may you give us advise what to do because in that subdivision we are the only one without secondary line which means we won't have electricity and our garage is useless because the post is the middle of the house. Before we bought it we were not informed that there is no secondary line. Please advise what legal moves and procedures i need to do. Many thanks.
