I bought xiaomi redmi note 5 in april 2018. From last month it started giving me problems like it automatically got switching off, when i pressed power off button then it restarted, it was also hanging so i went to customer service center. They said me that they had reinstalled the software and these problems will not come again but it started giving me problem like hanging, automatically wifi disconnecting. So, i went to customer service center yesterday, they said that tere are no issues and didn't did anything and were dealing with me in very much bad manner. I am very much disappointed by your customer service center. I want solution for my problems as my mobile phone is in warranty.
