Vijay Sales — Haier Inverter Split AC not working since installation

Address:

Lajpat Nagar, Delhi

We booked this AC on May 14, 2022. It was delivered to our home on May 15, 2022. Haeir's technician came to install it on May 17, 2022. But then there's was no cooling. So we contacted Haeir and they came on May 20, 2022. They said they're no gas in it, they person who installed it they did it wrong. So we contacted Haeir technician on priority and they filled the gas. For some time it was working fine, cooling was good. At 12 am May 21, 2022 it stopped cooling. We contacted Haeir they said it might have some defect. They might have to open the outdoor fan. We contacted Vijay Sales on May 21, 2022 and they're not helping. They should be responsible as they sent a detective piece.
