Nokia Phones — phone not functions

Address:

103 GOKUL VILLAGE SECTOR 9 BY PASS NEAR, BHOLESHWAR,MAHADEV MANDIR POST TITARdi, Udaipur, Rajasthan, 313001

I bought nokia 7.1 just 4 months ago. Its not working fine. The functions like, flash light, mute while call, hold while call, bluetooth, hotspot, battery saver, do not disturb, get active automatically.

If i download any picture and video, this gets saved after 5 mins.

I tried to reach, customer care, and nokia care. They restarted and did some activities on my phone. Even this is not working fine, the problem is increasing and no one helping me. I did the best i can do, but the problem with the phone is not fixed till now.

Please help me.
