Complete disrespect and lack of communication

Unfortunately, we do not get an option to rate them 0 stars. They happy to push you sign their agreement for installation but when it comes to maintaining the relationship with the client, communicating any information on installation they actually have no idea what the hand is actually doing. Installation teams arrive on site and they still tell you that they are not starting the installation and are not on site. Over a month and we still have no feedback to where they are at of when it will be complete. It further amazes me that they continue to receive the same complaints consistently for over a year (thats as far back as I could bother to go) and yet nothing changes within the company. Do they really feel that safe that they do not have to worry about their customers and their unhappiness of them due to lack of communication and service. It is blatant disrespect to all their customers that they have no intention of sorting out their lack of service and communication.
