HP India — Not providing service for under warranty laptop

Address:

560100

I am using a hp note - probook g1 440.
Few days back some components of laptop stopped working - speakers and dvd drive. My laptop is still under warranty coverage. On 9/06/2017 i registered a complaint on hp customer support for the same, my case id was generated but till now no engineer has visited me to check the laptop. I tried contacting hp customer care again and every time hp team tells me that they will get back to me shortly but till now they have not provided me any solution.
