Hyundai Motor India — Venue

I have given my venue to the service center at Jhansi (Natraj hyundai, Gora machhia, Jahnsi) on 11 of may, which was a accidental case and had its insurance as well.
But till date my car has not been repaired.its over 4 months till date.
And whenever i call them they just say wait for 10 to 15 days more its now very late or i have to file a petition regarding this to the court.
