Samsung India — Cooling issue/gas leakage

Address:

600119

Complain : samsung ac is not cooling. Ref no : [protected] resolution : technician darwin ([protected]) came next day. I was not at my house. My parents were there and they have least knowledge about ac. Darwin told there is gas leakage issue and it will cost rs 3600/- to repair. He took rs 570/- as advance and told tomorrow another technician will come for the fix and will take rest of he amount rs 3030/- after fixing the ac. My concern : why there is a gas leakage issue when the ac is not that old?? The ac on the other room is working fine. So this should be considered as the manufacturing defect and service should be provided under warranty.
