Sony India — unhappy with service

Address:

Bangalore, Karnataka

i bought sony mobile Experia C now i got the update as to update my mobile.While updating the mobile my mobile got switched off and when i switched on it came as sony and didnt on further. so i called customer care they asked me to press power button and volume up key still it didnt get switched on so they asked me to take to service center. So i took my mobile to Sony service center to address #65 ground fl 17d main opp kormamgala club 6th block kormangala.here i am not satisfied with the service they provide they are so arrogant.If i go with the compliant mentioned above the are telling it is water damage and it should be replaced eventhough there was no water damage. So i asked for standby phone as i dont have any other phone they are not ready to give standby phone also and people in service center is also very arrogant they dont know how to treat customer.so i am really unhappy with the service and this will insist me not to advice sony phone to any one so kindly do needful
