Sony India — Worst service

It was a very bad experience regarding your sony service sir.
I own sony xperia z ultra purchased in March of 2015.
Hence as you can check put i still have warranty left.
Problems in my phone:
1)my phone's charging port cover has loosened.
2)my phone's speaker has some disturbance.
3)my power button went inside.

I went to the bearest service centre and showed then the ORIGINAL bill and requested them to solve the problem.

Solution they said was
1)our company doesn't provide spare parts for z ultra hence your mobile can't be water proof from now
2)speakers are not covered under warranty.better option is pay us 10k and get new phone replaced (in some mannerless view)
3)the same reason..buttons are not given under warranty.pay us 10k and get phone repleced.


What i want to ask your company actually is:
Why for you guys give warranty if internal parts are not covered under it as it is a manufacturer defect???
Why for you don't send spares to them??
What items are covered under warranty if only speakers are not covered in it??
And finally why you guys appoint such guys who degrade the goodwill of your company??

I have a sony LCD 46", sony home theatre etc., and im using them since 3years and didn't get this type of BAD AND LOW QUALITY service!
When i shifted using apple to sony mobile and after checking out this type of defective mobiles and this type of disrespectful employees i am thinking that i made a big mistake.
Hope you guys please rectify the above said issue and hope contact me for further details.
