Samsung Double door Fridge

Hello. I purchased a Samsung Double door fridge at Samsung store in Kollonade in 2020. A year later the fridge started to freeze the food every morning on the refrigerator side. I lodged a complaint and sent an email to technical support unit. It took 2months for Samsung to send a technician. At long last the technician came and changed what supposedly was the part that caused the fault, however it did not stop. I have been calling since Jan and now we are in April noone has responded or come back to me. I have been using Damsung products all mg life but this is the worst experience I have ever faced.
