Samsung — I have been seeing the camera issue for the last 7 months

I bought Samsung M30 mobile last year. I have been seeing the camera issue for the last 7 months. On checking online in samsung forums, this issue seems to be with the mother board and camera. As the mobile is under warranty, I gave the mobile to Chrompet service center. They are rejecting warranty as the display is slightly cracked and it will not be covered under warranty. I asked the rep to change the display for a cost of 4500 Rs. The rep accepted and said, the mother board and camera will be covered under warranty.

After 20 days, now they are saying it will cost Rs. 13, 000 for service. I bought the mobile for Rs.10, 000 and service coat is Rs. 13, 000. This will happen only with samsung. Please order samsung to cover the mother board and camera charges as the mobile is still under warranty.
