Help with Nokia 5250

Pls can someone help me with my nokia 5250 issues. I just bought it brand new last december. It fell down heavily on hard surfaces and since then, it's started hanging (freezing) very annoyingly for days without remedy whatsoever, until it starts responding by itself again whenever it wants to. This is such times that it's decided to respond. Pls help.

Rather than asking here you can go to the nokia service center, so that they can have a look at your mobile and find the fault. Without looking at the mobile no one will be able to give you a solution.
