[Resolved]  Sony India — Sony Mobile Handset (Phone) issue

I bought Sony mobile phone Model No. E2363 (M4 Aqua) in the month of June’15 and within week I have started facing many problems (not ringing, call drop, data card not detecting) so visited Sony centre (complaint ID W115061803281) on 18th June’15 and they updated software and gave it back. But after few days same all problems started and I visited Sony centre again (complaint ID 15062702813) on 27th June’15 and they did the same thing software update and gave it back. But again within couple of days same all problems started so I went Sony centre (complaint ID 15063001602) on 30th June’15 and requested to change the handset and they changed hand Set but don’t think it was new handset because it was in open box. Box seal was broken. And now after two months again we are facing problems (Vibration not working, sometimes not ringing, over heating) and again submitted handset to Sony Centre (complaint ID 15092600256) today, 26th September’15 Since I bought this handset it became headache for me. It is really frustrating to format your phone again and again and remove your data and submit to Sony centre. Again & again submitted handset destroys my memory card and wastes my money on screen guard. Now I want my money to be refund
