Sony Xperia L Display Problem

[Dynamite]

My XL has got some display problem. During the past week small dotted black colour horz. lines have been formed on the phone's display at the bottom. Now, they have spread all over the display frm top to bottom. I took it to nearest sony service centre.They said its display problem due to keeping it in tight pockets.So, warranty service is not available for this piece.They said it costs 6600INR to repair the phone. 

There is nothing wrong in me ..... I have used the phone just like others used. What can i do now ....... PLEASE HELP ME
