Absolutely shocking. The staff on the phone was absolutely worst. We got a Brivis Heating only used for 1 week when realized it't not working OK. Needs reset every morning or when OFF for a longer time. While Brivis advised they can service it but they'll charge outcall fee. They said to get installer fix it as it's still a new install. Fair enough. But DandyAir refused at all. The words like Can't Do..NO... Can't Do..Get Brivis to fix it.. Then they realized their computer was down (or claimed it's down now). I can't do it! They were too rude! I asked Henley (builder) to call them but he got same answer.
