Sony India — Irreegular woking of mobile

Address:

Agra, Uttar Pradesh

Respected sir,
This is my second time complain against the company ...when i had given the first complain i was given assurance by the sony centre that i will be given a new mobile on their request so i backstepped from the complain to cooperate with them ...but now they are not giving me a positive response ..also since i have bought this mobile, either its with the shopkeeper or with the sony centre for recovery due to which my gaurantee period is affected ...so i would like you to ponder over my problem and extend my gaurantee period..
I have purchased sony XperiaT3(Imei number - [protected])(model -D5102, Black) from Suryansh communication sanjay place (address-block no-41/2G, sanjay place agra) On 5th june 2015. I facing many problems while using my phone like -heating problem, while my phone is unplugged then also charging sign is shown above with improper and fluctuations of battery usage, in camera -time burst effect backs itself, pattern lock not working, on first time using of Google Chrome and play store message occurs-" unfortunately Google Chrome/play store has stopped working"respectively, Back key is not working while using whatsapp. I went to the shop from where I have purchased (mentionedabove) on 7th June (exactly after 2days of purchase) for complain but in response I got that I have to wait for 15 days unless an update of lollipop version occurs and I wasn't informed that I can replace my phone in 7 days, I have one year insurance... Also I went 5 to 6 times to authorized service centre near subhash park agra(ankur care centre), but they were unable to resolve my problem... I kindly request to intervene my problems resolve it as soon as possible or give me cash or you can also give another model of this company ..or I have to take a legal action against company..

After one replacement of my mobile they had given another mobile to me with same problems as before.
