Samsung — Refrigerator

I have raised a complaint regarding my convertible freezer, where I observe that even when the Freezer is converted to fridge, the cooling is like freezer.

For that the technician had come and said it might be freezer duct or PCB, up on asking repeated questions Like how do you know that pcb is really an issue, it might be the sensor in duct as well. He checked with multi meter for duct and confirmed its PCB and he replaced the PCB by charging ~1500 (incl. service charges).

Now even after replacement I see the same issue, Now he says the duct is a problem and needs to be replaced.

This is the way they are cheating, probably my old PCB is good but because of him i had replace and now i have to pay extra for duct as well.
