Nokia care center sucks

I had very worst experience with Nokia Care Center , I had minor software upgradetion problem in my Nokia 6680 and i went to the following nokia care center.

Samvradhi Technologies
A/4 Khb Colony,Koramangala, 5Th Block, 80Ft Main Road, ( Land Mark)Opp To New Shanthi Sagar., Next To Airtel Office Cross Road)., Koramagala, Bangalore-560095
Phone: 080 41224127
Email: samruthi_koramangala@nokiacareindia.com

Now the best part of story begin.
Day First : I went to that shop and asked for my cell repairing they said that will take 3 days.

Third day: I called them around 11:00AM they are not picking up the phone,
Fifth day: I called them again but still no response.
Six day : I went there and asked for my Cell, they said that they haven't fixed it because of the many customer . I asked for cell back so they have taken 100 Rs for inspection charges .
I really don't understand that what exactly they have inspected . when i called customer care they said that you don't have to pay them. Finally they said that the phone which i am using, i bought it out from india. Now the question come that when i went first time why they haven't told me same thing.

Conclusion : Conclusion is don't ever ever go to this Nokia Cara center .I will suggest that you can go to any local repair shop But don't go to "THIS" care center.
