Worst service experience

This company has no support staff that you can communicate with, or email. I have been waiting for hours on end on the phone to get assistance. Their installer, merely installed the cabling and unit and stated there a loss problem and left with no fault reference., stating his technicians will be back to resolve the issue that very same day. I have paid upfront and was advised I would be connected on the day of the installation, now I have no service as I have cancelled my other packages.
