Boat — boat bass 225 red

I have ordered 1 month back but it is not working properly. So i have registered my complaint to boat, but it is showing that your status is approved and complaint is registered. Now i am not having any response from them. Even i make call to them no response. 20 days back i have registered my complaint to boat company. After the registration i got one ticket for complaint of my product. On 8th august i have registered. Now it is showing that your order is approved but i am not having any response from them
