Don't purchase Gree

GREE AIR-CONDITIONER NEVER WORKED

I have recently purchased a totally refurbished smart house with a brand new Gree unit installed. No one had lived in the house since the Gree was installed.
And even though the previous owners gave us all the paper work for the supply and purchase including the warranty, Gree would not honur the warranty as I am not the original purchaser.

Not acceptable Gree .
