Cable card problems

I own 2 tivos a  bolt and roamio  lost HD channels on both of the October 3 or 4 th. TiVo  guide is correct but channels are all over the place 1008 should be ABC but is channel 1003 CBS a lot of channels are V 53 and cannot find most of my channels. I still have the lower channel numbers are correct. Have spent hours on the phone with Comcast had a Comcast guy came in for almost 2 hours said he would look into it. Never heard back from him. I keep talking to the Phillipines nice people but do not understand my problem. Is there someone in the software technical dept iin th US  that can help.  I talked to TIVO  they want a current guide list to check the problem out.I cannot get one from anyone. I don’t think it’s a tivo problem since the guide is right and both my tivos are doing the same crazy channels.  

I have had this problem over a month and many hours waiting on the phone and getting disconnected waiting for a supervisor.  I read something on a tivo forum that says the pairing could be incorrect on the conditional access page.  Can someone please help to get this fixed they were both working fine before something happened that day. My other cable tvs are working correctly with the cable boxes.
