Cable card

On Nov 3rd, we started getting the V59 error on all of our channels. We use TiVo with a cable card. I suspect Xfinity deactivated the card, as I see messages from others that they had the same issue on the same date. We did get a notification that Xfinity was going to stop giving out cable cards on Oct 24. We have tried calling support, to no avail. Also, our Internet is dropping often throughout the day. Is there any hope of getting our TiVo configuration working again?
