The study was conducted by Michigan-based CFI Group. It finds higher customer satisfaction scores for telecom players, based on their history of providing better customer service, said Phil Doriot, one of the study’s authors.
That is consistent with other studies, but might be of limited predictive value. Cable "satisfaction" scores generally are low, but that has not lead to wholesale abandonment by consumers, even when satellite and telco alternatives are available.
"Not so happy" does not lead directly to switching behavior, it would seem.
