Nokia (N5610) — Please help me

Respected sir/mam,

With due respect it is to inform you that I had purchased a mobile N5610 IMEI NO:-[protected] on 15th March 2008. After 2-3 days my handset was Display Blank. Many times I had complained to the Nokia Care and every times they said that they have changed the parts but each time I am having the same problem from March 2008 – Feb 2009. And they told me that if the handset is opened for more than 3 times and if the same problem is repeated again & again they are going to swap my handset with N73. But whenever I received my handset I have to submit it back within 2 days. I hardly used my handset for 30 days.The Nokia has harassed me a lot from last 1 year.
Consumer Court is my last attempt for help I hope you will consider my problem and solve it as soon as possible. I am sending you all the details (like my email, job sheet and purchase bill) of the Nokia. Please help me as soon as possible. Please reply me soon.

Thanking you,
Your sincerely,
