Xenos Automotive — central lock in warranty period but not getting support

Address:

Kolkata, West Bengal, 700099

I had brought the rotweller central lock in December 2017. From july 2018 it is not working. Complained on August 1st2018. But the technician never visited. Again called today. Customer care executive connected to the service head of Kolkata Mr.Devender. he was very rude. He said it will be only done when i bring the car to their service center. Is this the kind of service that xenos offers and keeps such rude staffs.I want a resolution else i will complain to the consumer forum.
