CableCard Activation/Repair

I have two existing, previously activated CableCARDs in two TiVo Roamios. Both lost authorization simultaneously immediately after an Xfinity power/service outage, and every channel now returns V58. This is not an individual TiVo reboot or channel-package issue. I have tried activation on my end with not luck and cannot get a single Xfinity customer rep that will listen to my specific issue, let alone the required steps to fix it. I need advanced repair to verify that both CableCARD serial numbers remain assigned to my account with the correct CableCARD equipment codes. I need someone at Xfinity to please check their Host ID and Data ID pairing and validation, then send an initialization/refresh and entitlement signal - If the cards have no OOB lock or VCT information, then please open a local headend/legacy CableCARD outage ticket. I have gotten nowhere with Xfinity support thus far and know this is not an issue that will be resolved by a technician visit. I just need someone who understands what I am describing and can follow the steps I have outlined.
