Hi.
You may get faster responses by posting this in the correct forum board.
However your options could be to ask the shop where you bought it to get a quote to have it repaired by an authorised engineer.
If it still works put up with the damage until you can upgrade.
If its a crack get a case and screen protector which can mask slight cracks.
Take it to a standalone shop for repair.
Order a screen yourself and replace it yourself if your competent to do this.
The last two suggestions will invalidate any remaining warranty and should really be undertaken if your warranty has already expired.
