[Resolved]  Samsung Mobile C3303i — Mobile Hang & not work

I had purchased Samsung mobile C3303i mobile one month before whose IMEI:-356361/04/923124/0 & s/n : RPKB867015p.
After 3 or 4 days of purchase it hangs automatically and always show connect PC suite on the screen & when i switched off the mobile it automatically show Battery charging. when i complaint about this to the shop from where i purchased this, he told me to go service center for repairing & other thing. why should i do this, even after purchased of a new set & problem came just after four days.

I just want replacement of set.
