Nokia 3 bugs

Dubhem

My nokia 3 has been showing emergency call for like 2 weeks now..it recognises the sim cards but..i  have not been able to make use of it for call or data since then...even after so many factory resets and booting into safe mode hoping it would resolve the issue.. Today, the volume slide bar goes to zero/mute for no reason..even after factory reset ...the issue is not still solved..
Please what should i do... am running Android 9 pie August security patch..
