Sony India — misusing the mobile

Address:

575002

As there was problem in my sony xperia z1 i couldn't transfer the data also couldn't open it i gave it for service center in velancia opp more super market mangalore branch they have told me that it takes 25 days to get back the mobile. And i came to know that your service center people had been using my applications such as facebook also tried my banking application to login and they failed and my banking id has been deactivated. When v came to know and asked abt this in the service centre they have been telling that they couldn't flash it when directly send to bangalore service branch. Now i want response that whom should i blame and if in the future any problem occurs to me who s going to b responsible. I had many personal details in that if anything is misused defiantly i am going to take action on sony service centre.. I have been a sony custom since 4 years the trust which i had is total broken and also hearafter idefinitely suggest other not to go for sony. Whatever it is now i need a proper clarification and justification for this
