Maruti Suzuki India — ac repairing

Address:

Yamuna Nagar, Haryana, 135102

I have asked to repair my maruti zen car ac. First they have told me it can be reoaired and will cost around[protected]. I agreed they charged 1700 but till now ac is not working and i have to visit the service centre every alternate day for the same. Now they are telling that its cooling coil may have problem, new is not available in the market, they will arrange used one which will cost another 2000. Plz. Look after, other wise i shall approach to consumer curt.
