I don't have any hope that writing this letter will fix my problem or not. But Still…

I have Sony Ericsson Vivaz (U5i) and faced some display Problem, hence I gave it to your Authorized Service Center (Phone Zone, Chennai) on 15th November, 2010. Still I didn’t get the phone back. Whenever I call the service Center (Phone Zone) they are saying that parts are not shipped and not giving the proper delivery date. Hence I called the Sony Ericsson Call Center at 39011111. I spoke to 4 different guys including couple of escalation representative, I didn’t get any proper response they simply saying call us after 4 days on each phone call made every 4 days. Not sure whether you guys are dragging my warranty period or what????

Here is my case no : 88926843
