I think the management is already informed:

I received a Private Massage from my post in Tipidpc.com from the Owner:

Sir Zeroy,

I am Edmund Uy, the dealer of the Caltex Commonwealth station that you are complaining about. I would like to apologize for the incident. Our fuel pumps, admittedly, at times, get broken because of frequent use. But our pumps are all Doe accredited and I am not sure how this thing happened. I should work just like a calculator, Volume x price = total amount due. Our pumps are calibrated by city hall, handled by a Chevron contractor for repairs, and we just set the price. We cannot fix the electronics of the pumps ourselves, we are not capable. The only thing we can do is clean it & change the hoses & nozzles. the insides is off-limits to us.

Please accept my apologies for what happened. I understand the difference has already been refunded? May I invite you to visit the station or at least call or text me (0917#######) to help clear the matter.

Pasensya na po uli, hindi po namin sinadya o kayang sadyain yung nangyari.

Edmund Uy
