Hello,
I am harshit dave. I m appreciate xiomi for making such wonderful mobile phones. And i am regular customer of xiomi. And i have been using redmi note 3 since last 6 month. It works perfectly. And i refer all to buy this phone. Its only 6th month old. Suddenly yesterday it was switched off due to low battery. And i put for charging, but i saw that phone didnt start. Then i go to mi store in ahmedabad. Where i live. I wonder all the branches. But no one can satisfy me. Specially bodakdev branch's representative. Her name is bhargavi. She talks very rude to all customer. Then i go to bapunagar branch. And in c. G road and bodakdev and c. G road branch's technician says its only battery problem and battery is out of stock now. So please go to bapunagar branch and collect it. Your problem will solve. And when bapunagar branch's technician check he says there is a motherboard problem and all. So everyone has different opinion. I cant understand whats the hell is happening. I was suffering from 10 a. M to 9;00 p. M without lauch and dinner. And still i didn't get any solution. I just cant understand its only 6 months and how can its possible. So please help me i request you. I love xiomi a lot. Its a humble request. Please solve my problem i can claim on company i can do strick steps but due to my last expereince i dont want to do such things. So i am waiting for your response.
