Installers dont have to call, But the customer does have a right to call Directv to complain if the installer does not show up within the time frame. Yet the installers on this site bitch about the same customers for doing so. The customers dont know or care about the inner workings between Directv and the installation companies, All the customer wants is what they have been told at the time they were told it would happen. I think the installers think the customer has nothing better to do than sit around and wait for a installer who might or might not show up. I DO have to take time off work for the installations. It might not be the installers fault BUT its definitly not the customers fault.
