Just Click Services - Services are not appropriate

There was frosting issue with the Refrigerator when contacted Just click services they sent their Technician Mr. Abdullah (**********) who stated that the fridge has not working on Auto deep frost mode and because of which the complete fridge has problem, he changed CP Damper Set with deep Frost Injector Part which costed around Rs.**** along with service charges. He asked to switch on the fridge after ** hours and after switching on the fridge after ** hours the Mother Board (PCB) got bursted and there is no response from the Service people too. When contacted LG Services they clearly stated that because of incorporation of the Damper the PCB has bursted and there is no replacement as the Refrigerator is * to * years old model. Hence I am clamming the complete loss of refrigerator Rs.***** from Just Click Services(**********)
