Cebu Pacific Air complaint: Constant change of schedule

Ref DCDBUI
When we originally booked this flight, the orig date of return to Manila was June 7 noon.
1st move – flight moved to an earlier time to 9AM same date June 7.
Sometime on June 5th, we were informed flight cancelled and moved to June 10 at 9am.
So the passenger is already on his way from Mlang, N Cotabato June 9 late pm to be able to be in airport at 7am on June 10.
We were informed of another change to June 10 but 10:35pm. When we clicked accept and then checked in, it changed again to June 11 2:05am.
We have to other choice but to accept the changes as it is now very expensive to get another flight to Manila. So inconsiderate of Cebu Pacific. Ok to change schedule but same day; but to change 3-4 days after is so insensitive to the plight of the passengers and changing the date just a day or two before the flight is too much.
