Mackay Renewable Energy

It's a pity they don't have negative stars on this! Firstly they wired the solar in incorrectly so every kilowatt generated was charged to us. We went from a $400 power bill to $1000. Then they blamed other electricity supply for the problem! Other electricity supply were nice enough to come out and have a look at the problem. They confirmed it was wired incorrectly. We went back to Mackay renewable with all the information, they sent a sparky to fix the problem. The sparky came and did something, our power has gone back down to $400. I don't think the panels a generating anything. We asked for our power bills to be refunded. They agreed but nothing has happened after numerous calls. It's been a year and a half now. We spent ~$9k on something that doesn't work, which we've had to cop out more cash (~$700) on.
