[Resolved]  LG / Kp199 Cellular Phone — not working keypad or can't on

Dear Sir,
My Mobile model is LG KP199, Sl.No. 808ACGW082495.
I am a LG KP199 mobile user, I have purchased a new connection from LG show room, Mahaboobnager, A.P. on 10.11.2008 with LG mobile show room, The cell is not working with in short period I found that I am unable to key pad operation, i.e unable to switch ON the set or switch off it. So I have given my set to your ACS at Mahbubnagar, AP. ( Sri Chakra mobile care centre ) for service twice on 14.02.09 and 21.02.09, but till now the problem not solved. Due to my work busy I am not able to go the service centre every day. So please tell the cell working or not. If not working what is the procedure to get new cell, as it is under one year warrenty.
Please help me.
Thanking you Sir,
B.ChandraMohan,
