Neighbor infront of house leaves signage all night

Posting on behalf of my gf. They live sa Burnham area infront of one of the hotel. Recently neighboring hotel put up a store but they leave the signage on all night and it's so bright na umaabot na sa kanyang room (6+ storey apartment). Ilang weeks na but di pinapatay. Telling her to talk directly sa owner or manager but kung di gagalaw. Saan ba pwede magescalate? Di ko lang anung ordinance kung meron pwedeng icite
