Motorola Solutions — authorised service centre are ignoring my problem

Address:

756100

I am from bhadrak odisha,
I own a motorola g5s and i bought it before 3-4 months.
But due to some problem the camera stopped working so i went to the service centre which is in nayabazaar bhadrak...
They kept my phone for 4 days and returned me by giving a worst reason i told ok no problem but the condition was so worst that the display was no fixed properly the sim slot was not there and the flash light was not working... And now when i am telling them to fix my problem... Reply from them is... We are not responsible for this we don't know about this...
So it's my humble request to solve my problem.. Otherwose i will file a case against them...
