Coolpad India — coolpad note 5 mobile service in warranty period

I purchased coolpad note 5 from amazon, when i bought this phone they have delivered me the duplicate charge of my phone, as there is no such coolpad logo or sign on the charger and sooner it started showing notification that disable harmful app, (Themes) again and again. And i can't even uninstall the app.. And it also shows unfortunately cool manager has stopped. Battery doesn't even lasts 12hrs.. I had a prob. Of heating and lcd lines i submitted to the service center on 20.12.17.. Every time they are saying ensure next week. I am unable to understand appropriate date..2.5months has gone.. But still i didn't get my phone.. I need my phone immediately. If i didn't get it.. I will move it legally..
