I called the number (02) 4275 7522 back and spoke with Alice. I reached Blue Scope Steel. I asked if they were trying to sell me something and she said they are not selling anything. They are like a manufacturing company. They make steel. They are based in NSW. I asked to be taken off from their list and she said they do not have a list. She said that someone could have tried to dial a number that's close to my number.
