Nokia Mobile Battery (Bp - 5m) — Poor Servie of service center

Dear Sir/Mam
I bought a New Nokia 6500 Phone on 27 Nov 2008 from Garg Eletronics, Mathura Uttar Predesh. On last 26 May 2009 (Before end of my battery warranty) I was submitted my battery for REPLACEMENT (at Nokia Care Zone, Siddhi Vinayak, No 20 Govindpuri Colony, New Sanganer Road, Sodala, Jaipur) because it is goes to much HEAT UP while using. They are tell me that we will return your battery with in 10-12 days. After 11 days I was to call at service center, then they tell me for Monday but I was contect with them on Tuesday( 9 june 2009) now they tell me for next day. I required my battey urgently so i was go at service center on Thursday (11 june 2009) now they tell me for next week. I was talk with Manager for the battery then he was also says for next week.
A web site is given in the job sheet "www.namescareonline.com" for check your job sheet status I was check my job sheet status on thursday (9 june 2009), then according to them my job sheet is colsed they dispatch my battery to nokia service center, then why service center is not give my battery?
Because they tell me for 10-12 days I was submitted my mobile battery otherwise i can not deposite battery.
First thing they tell me lie about battery returning date, they me on 6 june 2009, but they mention on job sheet 13 june 2009.
Now what will I do, because I am required my battery urgently.

My jobsheet number is[protected]/090526/37 given by Nokia care.
