They are nothing more than scam artists. I leased a new retail property and they were the default electrical supplier out of contract which means charges can be quite high. That i accept what i don't accept is them not sending a billl for 3 months and the lying saying they did. Then when i make a complaint because i hadn't received a bill even though the charges are extortionate they just transfer it to a debt collection company. I've not heard anything from opus despite making a complaint to them. When i rang opus to discuss the 3 month bill they then offer to backdate the bill to a more reasonable amount if you sign a 2 year contract with them. this sounds great apart from the fact that their rates are roughly twice as high as octopus. So you actually end up paying more over the two years. Just make your life easier and avoid at all costs.
