Tata Motors — Car repairing with non genuine parts

I have serviced my cars in focuz motor last year and they told the front suspension has gone so we should replace it. And I told them to replace it.
And now after one year when I have taken car again for service to one another service center they told that the front suspension is not working properly and they checked it and told that the focuz motors have replaced the suspension with non genuine parts which is second quality.
