My mobile was not able to make & recieve calls. So I went to the Nokia Care Center: "Manav Communications" shop No.2, A-2, DDA Market, Paschim Vihar, New Delhi-110063. There I gave my phone to Mr. Azad who locked my phonebook & consequently I lost all my 200 contacts numbers. when I try to open my phone memory, a pin code number is asked. Mr.Azad is not accepting his mistake & says that he can do nothing to get my data back & re-activate my phone memory. He says that he will have to flash the phone which might cause my phone to become dead. I want my important contact numbers back, so I request you to take action as early as possible, otherwise I will have to go to CONSUMER Forum. Thank You.
