The installer should do what the agreement says which is wire 4 rooms. That IS what he is being paid to do. ANd if he doesnt feel he is paid enough he should hit the road and find a different job. Otherwise he is cheating the customer. If it were me and he refused to do the work I would be on the phone immediately telling the satellite company about their subcontractor who refuses to honor the agreement.
Only for two twin tuners or four receivers!!!
One twin tuner installs get two rooms - per agreement. More tvs/rooms are extra charge.
