Symphony Limited — Defective cooler

I have purchased symphony diet I-55 cooler on 6th March from Bajaj electronics gajuwaka branch. After bringing cooler I have checked the cooler it was damaged and the cooler option is not working. I have raised complaint to Bajaj electronics immediately but there was bad response from them and symphony executive visited my home after couple of days but he clearly said it’s a damage product and he can’t do the repair.
As it’s a new piece and was delivered a damaged product I need a new product to be replaced. Look forward to get response from symphony team
