Condo electric meter is swapped with neighbor?

So we live in a condo in Taguig. And there was this time when our neighbor unit got a disconnection notice at their door. At first I didn't mind but then it's been their for a week or so. Then one day, pag pasok ko ng unit namin, we were disconnected as well? So i got the condo maintenance to check what happened and he couldn't actually figure out at first. He then called the elec people to check and turns out our electric wiring is swapped with the unit beside us FOR 4 YEARS.

I asked them do i need to file anything but they said sila na bahala and will fix it with Meralco soon. i think 3-5 months have passed until they actually notified me that their going to swap the wiring and meters para match na with the units.

Im just curious if we're supposed to pay something or refund from something since basically our bill for 3-4 years of living in this unit is not ours ever since we started paying it. Any thoughts?
