HTC India — htc desire 828 mobile

Address:

Khordha, Odisha, 751006

I have bought this htc 828desire on 4th march 2017. But this is the 5th time in 6 months i am having the same issue of the phone suddenly getting switched off and not starting till i take it to the service centre to repair. I have requested many times to change the handset but nobody responded. Everytime they keep the mobile for two three days and then return assuring no such problem will occur in future but its sad, it does following which iam now forced to go the consumer court. Iam a doctor by profession and i keep important datas in my phone but it gets erased everytime they format the phone and iam tired of visiting the service center every month.
