Caller ID on T.V. screen

My caller ID that comes up on the bottom of the T.V. screen, was working fine, then one day it just quit. I have chatted with 3 or 4 different people, reset the cable box, did everything they told me to do. It still doesn't work. They said a service tech would have to come out and, there would be a charge of $60.00. I'am wondering if maybe the service was turned off and, maybe just needs to be turned back on. I don't know how it works, But I know I don't have the $60.00 for a service call, I already pay $250.00 a month. Does anybody have any suggestions?
