Tenure Bridge Request: Diamond Status Reset After Plan Change

Hello, I recently helped my mother set up a new 1Gbps promotional plan ($50/mo) at our current address. We kept her existing Xfinity ID, but the new account is showing as Silver Tier, while her previous account at this same address was Diamond Tier.

Per the Xfinity Rewards Terms and Conditions (Section 3), tenure should be based on the member's longest continuous service. Since this is the same household and same Primary user, I am requesting a Tenure Bridge to restore her Diamond status to the new active account.

I have both account numbers ready to provide via Direct Message. Can an official employee help me open a ticket to backdate the service start date?
