Stuck at 89% acquiring channels Tivo

Cox cable orange county- looks like there are others here that are having the exact same issue. Getting very tired of the finger pointing back and forth. We've gone through numerous cable cards, tuning adapters, two Bolts and now a Roamio, at least 5 techs with probably over 40 hours of time at our house and probably double that amount of time spent on the phone between Tivo and Cox support. Last Cox tech said that the issue was isolated to the Bolt and to get a Roamio and they could get that going. Ordered the Roamio and the same exact issue persists. This is beyond frustrating. Of note, someone I know with a Tivo Roamio that is working properly with cable card and TA also in OC brought their box and TA over to my house and it fired up instantly upon plugging in the coax (done with cox technician). So that eliminated signal and configuration dissues. I would appreciate assistance from someone at Cox with advanced cablecard/Tivo knowledge to get this up and running. The last tech left a contour system at our house and said we wouldn't be billed and that is showing on my account too and needs to be adjusted. Also two tech visits were also supposed to be adjusted but have not. This is beyond frustrating.
