Samsung — I am complaining about the digi touch refrigerator

I purchased samsung digi touch refrigerator on sept 2021, complain about defrost in jan2022 and complain again in march 2022. Executive told me unit will not work in future as well. I filed the replacement or refund but none of the solution was provided to me and samsung denied the solution they want me to get it fixed by replacing the door on a new unit which is not even 8 months old.
