Apple Service Center have such bad service. This was what happen.

At Machine's Service Center at Midvalley
Me : Hi, I dropped my ipad. Can you fix it?
Technician : Ketuk a bit with his fingers. Have you tried to reset it?
Me : Yes
Techinican : In that case, we cannot do anything. You can pay for a new ipad 2 replacement.
Me : Can't you open up and have a look inside?
Technician : Sorry. It is against apple service center to open up the ipad.
Me : FINE

At a generic phone shop (My favourite phone shop actually)
Me : Hi, I dropped my ipad. Can you fix it?
Techician : Let me look at it. Give me 4 days time. You can have your ipad back by tuesday.
Me : Seriously?
Techinician : Sure. No problem. But it is going to cost you RM280.
Me : OK.

Moral of the story, don't go to apple service center. They are unreliable and hopeless. All they want from you is to suck your blood.
