TV Channels Missing

For the past month our TBS channel (OKC channel 731) has not worked. The non-HD channel 62 works.. but HD 731 does not. We called the first time about 3 weeks ago.. and after running all of the tests they could not determine what was wrong. We were supposed to have received a call within 24-48 hours and did not. I called again a couple of days ago.. they ran more tests, had us check physical connections etc.. nothing helped. While we were waiting on the testing they were explaining the Contour and home phone bundling they were wanting us to "upgrade" to. By the end of the call, we had not signed up for the additional stuff and there was still no explanation for the missing TBS station. Now, FOX News and CNN are missing as well. Part of me feels like they went "missing" because we didn't sign up for their additional services. But I'm sure that's ridiculous. Has anyone else had this issue? Cox - if you're reading this - is there really no way we can get our channels back? I was told the channels would "definitely return" if we got the new contour box. But I really don't want to feel like I'm paying a ransom.
