Nokia C2 - 03 — nokia care is not repairing my mobile

Address:

Vadodara, Gujarat

i bought nokia mobile c2-03 from redyphone .
But from second i was having problem in this product.
It means i got defective peace

problems in mobile ar as following:
-Video is not playing
-Many time touch screen stops working
-many times it is being hanged
-music player is also not working
-it is not operating on given command even many times it works on that command which i hav not given

Than i went to the nokia care Add-dadndiya bajar,vadodara. I hoped that they will repair it .

I got my mobile and checked out It was working at nokia care than after some 2-3 hours it was behaving same as i hav given in to the care

Than i went back to the nokia they told me that there is software problem and we should give it in to the company and it will need 7 days i said ok.
After having mobile till 7 days with them they have didn't repaired this mobile.

And before 2 days i have again give this product to nokia care and i have got back my mobile today but the same result i got.
they are not responding as they have to .
i have spent lots of time and money behind traveling to that place .
Time is very precious for me as i am student.
