The F120 program was not only extensive, but also highly successful. With over 1.1 million Cox customers enrolled in this communications program, the F120 program led to lower customer attrition rates PLUS an incredible 4:1 return on investment. That is, for every $1 Cox spent on the program, they received $4 in return. This program was groundbreaking, award-winning, but most importantly, helped clarify communications between a cable provider and their customers. Something that only Cox has,and continues, to do.
