Cebu Pacific Air – Thieving crooks! Do not use!

My flight was changed with no notification. Was originaly from melb to manila and was changed by cebu to syd to manila. I only found out when i rang to confirm my booking. So i was forced to buy another flight from melb to sydney costing me an extra $687 which should be reimbursed but they refuse to!
They make me sick...Do not use this corrupt airline!
