[Resolved]  Sony Ericsson - Mobile P990i — Not repaired - Even Though in Guarantee

Sir,
I purchased Sony Ericsson mobile P990i through sify shopping web site http://shopping.sify.com/shopping online in Dec 07 wide Purchase order no. .s[protected]b
The mobile IMEI no. is[protected] and model is P990i. Invoice no. 2839 by N R Infotech, Mumbai 07
It was delivered to my Dombivali (Mumbai- India) address on 25th Dec 07.
Recently I have taken it to Sony Service center for some repair. ( LCD screen calibration problem)
Sony service center at Saki Naka is saying that this mobile was not sold in India and hence we will not consider guarantee period.
I feel cheated. The Sify site clearly mentioned guarantee period.
Even after buying mobile in India, making Rupee payment, I do not get guarantee.
I request you to help me.
Latest status: Sony Service Center say that mobile can not be repaired and they are returning it back. I have paid Rs.14000/- and within six months I have to throw the mobile since it can not be repaired also.
I have raised complaint with Sony Ericsson and their reference no. is 72430288.
I have also raised complaint with Sify Customer care and their reference no. is
7297070
Both parties did not give any solution so far.
Please help me to get a replacement phone.
Regards,
Vijay R Shrawage
