Polktronics

This company has absolutely no idea how to repair mobile phones.
My phone was returned after this company had said they had not touched it.
There was evidence they had tried to look at it, but had gone about it totally haphazard and with no idea.
The stylus was missing, and although they claim to have not touched it the evidence is to the contrary.
I have written twice, giving them chance to reply, but they have not even had the courtesy to acknowledge my correspondence.
I would therefore suggest you try a reputable company before you approach this one.
