Blackberry — mobile phone problem

Address:

Jaipur, Rajasthan

I had purchased a Blackberry 8520 handset on 20/01/2012 to do my business work through my cell.
From the past 15 days I am facing a problem with the phone...
The problem is that whenever a call is made or received...the sound from the earpiece starts cracking up...and I am unable to talk through this mobile...
I have gone to the service centers for 2-3 times for this matter...but those people are not understanding my problem only...
they say that i will have to drop the phone there which is impossible for me and that too for 20 working days.
that's ridiculous and PATHETIC!
i wasn't expecting such response from BB...more over they say that i wont b getting any stand bye phone...What is this????...other mobile companies like Samsung and Sony Ericsson provide with a stand bye piece...

I am fed up of this phone...i am attaching a snap of d foto...
hoping that my problem is resolved ASAP.
