Hyundai Motor India — defect in rendering service

Address: 110018

My santro car no. Dl 4 c r 2879.
I approached deep hyundai service centre at peera garhi, new delhi for regular service. My vehicle was picked up from my residence.
When i received back the car, it was having problems, 1) it's tyre was punctured, 2) steering was defective, and 3) air conditioning was not effective.
After complaint, i reached to got rectify. Only steering got corrected.
It was told that air conditioning pipe had leakage. I suspect this was result of service (As before service it was fine). It is still faulty and no one is attending to it. Will someone listen. I am now afraid of such type of services.
