Local 24 Hour Electrician

House company – I had a electrical problem where half of my house had no power on a Sunday. I have a regular electrician but he was not available so just looked on the internet and phoned them. They guarantee within 60 minutes they will attend. They didn't, they took 2 hours. After an hour and a half with no apology from them, I phoned and told them not to come and called another company. An electrician turned up and I assumed it was the other company that I had arranged after cancelling the first. They gave me a quote for $3000 and said they would have to replace some parts of the safety switches in the electricity panel and 8 power points. They said it was because my grandson used an old charger from his house for his iPhone. They were all finished and then the second company turned up to do the job. I thought it was the second company doing the job as I had cancelled the first company as they were too late. More fool me - should have checked their business card. Asked for a receipt, they said they would email me one, never came. In their webpage it just has a telephone number which I have called to ask for a receipt, sent them text messages and even threatened to take them to department of fair trading. Not one response back from them.
