Carrier Midea India — carrier ac purchange from vijay sales ,crown plaza faridabad

Address:

Faridabad, Haryana, 121001

I have visited vijay sales store, crown plaza faridabad for purchase window ac but after convincing by sales person for inverter ac that feature consuming less electricity, i have increased my budget and had purchase carrier split inverter 1.5 ton duracell 3i ac on 28/4/2018 from vijay sales. And installation done after two days. Engineer not given demo that time due electricity not available after not 15 days this is not cooling it's not even cool 12x10 room and consuming 18 to 22 unit in single night, i have given complain many times but engineer visited and checked the unit and told me that ac working but not solution provided him,
I have told to service engineer that please sit in the room and feel that room getting cool or not than he told me that as per given instruction by our superior, we will check our unit and make the report, if your room not getting cool or consuming heavy electricity that is not our concern.
I have written my feedback on his engineer visiting report but no response revived by vijay sales and carrier company.
I am extremely disappointed about the service provided by vijay sales and service central he charged me 40300 rs for that unit which is not working properly
False commitment given by sales team that this ac is consuming less electricity and now it is not given cooling properly.
Anybody here to listen my complain, provide me permanent solution or change my ac.
