Ben suggested that we should change to 4 tons A.C because existing one is spoiled. Next day he brought a new 4 ton AC, opened the box infront of us, then went on the roof to install. Everything seemed fine. 3 days later the place is still hot, called him he came and said that it will take some more time to cool down the restaurant. One week later still hot finally got angry and told him to give me the serial number so that I can call the manufacturer for warranty because Ben refused to come to check. He didn't give us the serial number next day we found out that he didn't install the 4 ton that he opened infront of us. While he was doing his stuff, he had an old machine in his van which he switched while we were not watching!! What a dishonest guy! He's an actor, pretender! Will never forget such dis honest people like him. We don't need people like that in our society! His license should really be suspended! Don't use him! He did end up changing it to another 3 ton air con refurbished ones but not worth the money we paid but couldn't do anything because money was already in his hand. Please learn from this. I don't like to give bad reviews but I had to do this because I hope he won't do it to others ever again!
