[Resolved]  Motorola Cell Phone A810 — Indifferent attitude of Service center people

I had purchased a Motorola A810 in October 2008. The model is Motorola A810.
The touchscreen of my phone stopped working around 3 months back. When i registered my complaint, the indication sticker in the battery compartment was found red, which they told is due to contact with water. Also they told me there is another such sticker on the mother board and if that is also found red, the warranty does not stand. Fortunately for me, the inside sticker was found white, but even then the staff here is not ready to repair / replace the touch screen due to which i am facing a lot of problems.
On top of that, the service center staff are projecting a cost of 80% of handset value for repair.
Please help me get out of this soup!!!
