Smarthouse did not attend my property on the scheduled day. It wasn't a big deal to me, but I called to find out why. Person I spoke with on phone was very arrogant and told me various stories telling me I cancelled the appointment, then apparently my wife cancelled the appointment (she never spoke with them), then apparently there never was an appointment, and then they said a technician attended the site but no-one was home. All of which I knew were false, and I had evidence to confirm this. Yet they still had the nerve to treat me like I was the idiot. Eventually someone called back and admitted the issue was 100% on their end - but very disappointed with the disrespect I received prior to that.
