Can anyone recommend a place that can fix a Nokia cellphone?

Nokia in Kyber Pass Rd refuse to have anything to do with it as it is a Hong Kong phone. They would not even take a look at it.

Phone is a Nokia 5610 XpressMusic which has a virus or problem and will not stay turned on. Starting it up does not allow it to say on long enough to even get to the factory restore menu.

Daughter loaded a game on it. Zelda Beta3. After putting it on the phone the menus were weird, then when deleting it that is when the phone started shutting down after turn on.

Also I would like the faceplate changed. It is quite a complex phone being a slider model so changing it is no easy task.
