Sales staff have no clue?

Although Metro Fibre had completed the house installation in the complex and left application forms. Metro sales staff had not advised that the main cable was not installed. After cancelling my contract with another network and applying for live connection only then was I told by technical staff advised that the main cable to the complex was only to be installed at the end of November, NO REASON why should I sign up with Metro Fibre? No feed back from sales staff, WHY
