Nandilath G Mart — Product and service

I have purchased a Voltas beko 7.8 semi automatic washing machine from your Kannur branch(Kerala). But i received a damaged product and its not working properly. i have contacted to the kannur branch to return my product .At that time they cut the phone call after that i have contacted several time but they are not ready to pick my number. I am not happy with this experience.
I need to return my product.
