Nokia X6 — sound transfer through microphone

Address:

Bilaspur, Himachal Pradesh

hello sir / mam

i am Ankur Sharma.I had bought a nokia x6 handset 8 months ago .
the EMIE no is [protected]
last month suddenly its touch sensors stopped working.When I went to Nokia Care (Bilaspur),they said that you had to change the touch . They had changed it worth Rs. 1800. although it was under warrenty.
also i had to update the software so they said that you had to send the cell to company.
when it came back from company i got another problem of microphone as mentioned above.
they again send it to company instead of replacing the microphone
when i asked them to replace the microphone , they again asked for Rs. 550
also i had not my cell phone since 15 days.
Acc. to nokia care (Bilaspur) they said that you got your cell in 7 or 8 days.

i just wanna know that is this all right of taking Rs. 1800 and again asking rs. 550 instead of replacing the whole thing.
Also i want to take a quick action on returning my cellphone back.
i shall be thankfull to u .
