Trap in Lift

Yesterday, almost traped in the Lift.

The Lift went up to level 12 and when open the door it got stuck, my friend start to push the door trying to force open it.

I told him not to do that, because it may cause the lift door to go OFF alignment and the door will get stuck even more.

So tried to call the number stated inside lift for help but the line cut off, but lucky after awhile the door close back and went down to level 9 and it open without difficulty.

Quickly went out of it and take another lift up and go home. Hew...
