Hyundai Motor India — service manual not received

Address:

2/399, Mount Poonamalle Road, Pushpa Nagar, Chennai, Chennai, Tamil Nadu, 600056

I missed my first service due to sales representative suresh, branch - aminjikarai handing over service manual after 6 months of vehicle purchase. I was asked to pay rs.6000 for the ac servicing. Now the showroom (Kattupakkam branch, chennai) is not ready to do 1st service after presenting the manual and also reimburse the money which they promised.

Following up since march

I have been sending emails and following up patiently since march. No one bothers to reply. I had been to kattupakkam branch, chennai twice which is 20 kms away from my home and they don't even bother to respond.
