Nokia c1
Very slow

Sir,

I bought a C1-01 mobile, But it was working very slow. when I press the button to view the contacts it takes 4-6 seconds to display the contacts. It works like that from purchase onwards. I showed in Nokia customer care, even though it was working like that only. there they told that "we have to format the cell and update the software", they repare for 20 minutes. but it was not working properly. Please help me. The mobile didnot fell any where. From purchase onwards it was not working properly.to view the message when we press the button it takes 5 sec, to view the missed calls also it takes 6 sec time, it was very slow
