Nokia 2626 — faulty handset

On 18.07.2008 I bought a new nokia 2626 handset from The Mobile Store, Moradabad
After few month the handset's Keypad start creating problem. Some of the Keys such as joy stick menu key not working.
Three times I give the handset in the nokia care centre but the problem not over. When I request to the Nokia care centre they send mobile to the company at 4th time service.
After 15 days the company send back after its repaired.
my handset still have the same problem, Now the Care centre is saying the warranty period of one year is over.

I request to Nokia please replace my Nokia 2626

Thanking You
