my cell loudspeaker was not working properly & I was not able to redial all pre-dialed/miss calls.I had to switch it off/on to make it work properly.so I contacted NokIA CARE MANGO jamshedpur(MAPLE).they upgraded software on 23/12/08.after 2-3 days the problem came again.now this center told me to change sim. I change sim.no result. Now they sent my phone to kolkata for repair.After few days when i went to collect,speaker was not working & back body was also damaged.I told them to give it in proper condition. Now they want charger & battery & will sent it for repair. What is happening. I am without phone from approx 45 days.Should I go to consumer court or what to do suggest.
