Cebu Pacific Air complaint: Luggage scam

I decided to avail of the 9 KG carry on luggage option and pay extra for some sports equipment.A small cricket bat set for my children as a gift, value $50
I also had in my bag a battery drill.I went on the Cebu pacific website to check but it was contradictory.Part said lithium batteries had to be carry on luggage and it said tools must be checked in.It turns out after I tried to go through security the battery I could take as carry on and the drill and cricket set had to be checked luggage.Because I was forced to check my luggage ( due to the battery drill) cebu pacific charged me $175. Then they said I had to pay another$175 for the cricket bat as it was a seperate item.This would far exceed the price of my international ticket I had purchased.This is a scam and just tricking customers of money.Most airlines will check a carry on bag for free if there is no other option.
