Vestar — vestar window ac not working. vestar comp is fraud

Address:

Agra, Uttar Pradesh, 282002

We have purchased one vestar window ac.ac machine not working. Problem of compressor, and compressor stops in a while after it is made on.ac is getting on but no cooling. Difficult to understand the problem. I also lodged complaint on customer care. But sorry to say, even engineer of vestar told that compressor is out of order and to be replaced by company as it's in warranty of 5 years, vestar service head mr arshad saifi (Ghaziabad) is not interested to provide new compressor and warranty of my ac is going to expire on 12 june 2019. Vestar is a fraud company. Plz help.

Please help
