@jblbr: Our Meralco bill usually ranges from ₱3k–₱5k, then bigla na lang umabot ng almost ₱14k. Instead of paying it right away, we questioned it. We documented everything, requested a meter inspection and bill validation, and after the investigation, Meralco applied over ₱10,000 in bill credits kaya naging ₱0.00 ang bill namin last June. The reason we disputed it? Lahat ng aircon namin ay LG with built-in energy consumption monitoring, so we always estimate our monthly bill based on actual usage and almost always tugma siya. It was only during those last two billing cycles na sobrang layo ng computation, so we knew something wasn’t right. If your electricity bill suddenly doubles or triples kahit wala namang significant change sa consumption ninyo, don’t be afraid to request a validation. It could save you thousands.
