Dear team,
We have purchased 2ton lloyd ac. Since of my purchased it is not working it starts and give cool air for 5 min and break its continuity. Many time company person came but he is unable to make it repair.
We have invested for office because we are exporter and here many fourier come at our office and it seems awkward.
Team we are assuming that it is not repairable and we want it to replace on urgent basis.
