[Resolved]  Nokia 2700 Classic — manufacturing defect in phone facial

Dear sir,
I bought nokia 2700 classic in the month of feb- 2010 from a mobile shop in kolkata.imie no.is [protected].The screen of facial is loose , it means when i talk for 5 minute the phone screen become foggy from inside. I think that the sealing is weak, but nokia care center told me that, the facial is not come under warranty.But i think this is the manufacturing defect.
