Cable cards and tuning adapters NOT working

I’m 4 weeks into this issue that nobody can resolve.   

I have 4 sets of cable cards and tuning adapters in 4 TiVo units.  About 4 weeks ago, I noticed that some channels were not working.   I also noticed that all 4 tuning adapters were flashing yellow (should be solid yellow).   I called and they “reset” my connection.   Didn’t work.  Did that again a few days later.  Still didn’t work.  They sent a tech to the home (which showed no issues. I then talked to a tech agent who couldn’t pair all my equipment and suggested that I swap them out.  Did that - all new (used) cards and adapters.   Called the 877-820-82xx number and got those partially paired on one TV (not the others).   They sent another tech to my house (no issues).  The last time I called tech she was able to pair ALL cards but I have limited service.  No sub channels (1 HBO, 1 Showtime, no EPIX, etc).  I subscribe to EVERY channel.   

Frustrated, I settled and decided to shelve my 4 TiVo’s and go with your IP TV service.  I ordered the Ultimate DVR service (record 24) with 4 HD boxes.  They had to upgrade my modem to facilitate it.  Said great - I’ll see it in a couple days.  Ended the call.  What I received from UPS was 2 old DVR’s with 4 clients and the new style modem.  When I called (yet again) they said the sent me that equipment because IP TV service isn’t available in my area. REALLY? 

I just want my cable cards to work so I can use my TiVos or receive the IP/cloud based DVR service like I was offered.  Can anybody help?
