Electrolux India — air condition machine not working at all

Address:

D/8/1 Parth Indraprastha tower , Behind Govt. colony , Gurukul drive-in road , vastrapur, 380052

I bought this ac in march 2018. Since than i am having problem. Four times engineer has visited and changed gas into the machine but still ac is not working properly. Lastly i had to pay extra 600 rupees to get the valve changed as executive told that if you wait to get service from company you will not get it.
Still i am facing issue in ac. Lastly i am not getting any support from dealer in ahmedabad "vijay sales" from where i have purchased same. They are saying we can't help as company is not supporting. I am feeling helpless and feel cheated by both the companies. My contact number is [protected]. I hope there could be a way i can get justice as promoted in consumer awareness program.
