Nokia — Service is so poor

Hi,

There is vibration problem in my cell, i gave it for repairing on 24.03.2008 at Nokia Care, Sector-2, Noida.
After 2 weeks i get it but at that time it is having signal problem, i again gave it to them, then after 3 weeks i get my cell, i used it for 1 day and again third time give it to them because of signal problem, They said that it will replace with the new set and it wil take a week long time.
But today 06.05.2008 i did not get my cell.Now they are saying it will take one more week.

I want my cell i working condition as soon as possible.
