OMG ... if you cracked the 12 inch display ... that's going to cost you your left and right kidney to replace ....

You can get Apple Authorized Service center to give you a quote ... be sure to bring a chair in case you faint
Alternatively, if you have the tools and since your warranty ain't going to cover cracked LCD anyway .... you can try to repair the unit yourself. Be sure to have the correct screwdrivers first.

You need the P5 Pentalobe Screwdriver (you can probably purchase this online from iFixit or google for it).

Then purchase the replacement screen yourself: https://world.taobao.com/item/521959479966....0.dwUWh1#detail (as an example) ... even here, the screen would cost you about RM 760 (without shipping fees from China).

Of course .... anything cheap is always better .... Malaysian style
