Nokia Cellphone Battery — Refusal to replace battery when under warranty

Address:

East Delhi, Delhi

Sir,
I am a corporate client and use a Nokia 6620 cell phone with BP-5M battery.I bought and replaced the battery on 23rd July,2011.It was under warranty till 23rd Jan,2012.Since it was not working properly and needed charging 2-3 times everyday,I approached Nokia care centre at Acharya Nikatan,New Delhi on 16th Jan at Delhi.They wanted to keep the phone with them for 5 days before battery could be arranged and replaced free of cost,as it was under warranty.This appeared to me a delaying tactic and was not acceptable as this phone is the lifeline for me.However,I agreed provided they give me a replacement battery for those 5 days.This was not agreed by Nokia.
After that it has been an extremely bad experience for me with Nokia service centres.Nobody is prepared to listen.They send "cut and paste" type responses and have now started telling that the battery is out of warranty(which is true as the warranty has palsed on 23rd Jan,2011).To me it appears to have been stage managed by Nokia guys.They refuse and frustrate the client to such an extent that he forgets about the free replacements and gives up.
I refuse to give up and want my grievance to be resolved asap-replacement of battery free of charge.
Pl do the needful and oblige.
Kind regards,
