Having gone through this several months ago, I can suggest using this interim period where Cox is "investigating" as an opportunity to explore other options. Its pretty easy to get an inexpensive Roku, or Chromecast or other items (assuming you don't already have a smart TV with something built into it) and use a free trial of Youtube TV or Sling TV or Hulu with Live TV or whatever, and see if stringing along while Cox is trying to get their stuff together is even worthwhile.
When I did this months ago, we found that the alternatives were not only better but cheaper and I won't be going back to Cox as a tv customer anytime soon. And as an added bonus, having an old PC running nearly continuously as my DVR using a cablecard, that we've now retired, has saved us between $5 and $10/month in electricity costs alone.
