Nexa — baleno brake failure

Address:

Faridabad, Haryana, 121002

Car brake is not reliable as it failed more than 3-4 times in last 6 months. How can we feel safe when there is no assureity of proper braking system? Brakes become hard & double paddle any time. Due to this major problem we had met with accidents more than 2times. Who will be responsible for this? Also in the actual the engineers found break vacuum system fail after examine the vehicle for the whole day and they have made a false history of the vehicle by just mentioning the hard brake in the history. I need an explanation why is this manipulations being done by the company.
Who will be responsible for our losses?
Despite this there is no satisfactory response from the dealer
