Paying a price by going budget with Air Asia

Received an sms this morning from Air Asia telling me that there is a reschedulement of flight timing. We booked our air tickets from Air Asia sometime back in June for our honeymoon to Bali. We chose Air Asia over other budget airlines as their timings were better and I guessed we paid more for the favourable time slots. It came as a rude shock that the timings have to be changed and I tried to call their hotline, which proved to be indeed very hot as I could never get through to a human being. So I went to their webby and left a message, hoping someone kind enough would bother to return my call and care to unravel this mystery to me. It didn't help that I found out on their webby that the airline actually has the same timing available, just with a different flight number. The airline must be prepared to give me a proper explanation and take on my firing questions, if not that be my first and last time flying with this airline! And I would make sure all my friends know what a service this airline can provide.

This is what I have written to Air Asia in my fiery mood but I hope they can make sense of it and call me asap to clear the air.

==================================================

Tried calling the hotline but to no avail. I received an sms this morning informing me about reschedulement of the flight timing of QZ8493 from 1000hrs to 1645hrs. It came as a rude shock as the flight timing of 1000hrs is the reason I chose Air Asia over other budget airlines even though I have to pay more for Air Asia. To my astonishment, when I visited Air Asia website, I am shocked to find that there is still a flight (QZ8491) departing 1000hrs from SIN to BALI on the same day! I wonder if this is a way to trick customers into buying the tickets, only to be informed later that the timing has to be rescheduled. I also wonder if flights are indeed available in that earlier timing, can Air Asia not transfer those who bought QZ8493 to QZ8491? If for some reasons that cannot be done, I would expect Air Asia to allow customers who bought tickets for QZ8493 to change their flight to QZ8491 without any charges or penalties. I hope to hear a good explanation with regard to this asap as we would be departing in a few weeks' time.
