The product and the install was perfect and the airconditioner is working brilliantly, completely cooling the whole lounge and kitchen down,however when I insisted on a 5kw system to put in my house I was yelled at and insulted and treated very badly by Jay who never apologized, mind you because he insisted on putting an 8kw system in my house which would have been totally unecessary....the 5kw system is working perfectly on 22 degrees and cools down the whole space including the kitchen, something Jay said would not happen!! I was very courteous to Jay over the phone in the meantime he was arrogant angry and insulting and it was completely uneccesary. When your client is upgrading from a 2kw system to a 5kw you should show some more respect and be happy that they continued to use you throughout the install especially after the tirade of insults...Terrible terrible treatment of a customer uneccessarily!! His workers said he is always like that, which makes me sad for them.
