Incorrect Customer Tenure After Move — Diamond Membership Status

I need assistance correcting my Xfinity Membership tenure.

I have been a Comcast/Xfinity customer continuously for more than 10 years and should have Diamond membership status.

When we moved in 2025, Xfinity created a new account instead of properly carrying over and linking our prior customer history. As a result, my current account incorrectly reflects a much shorter tenure and Gold membership status.

This issue was supposed to have been corrected previously, but it clearly was not.

I need an Xfinity employee to review my historical account tenure, link the prior customer history to my current account, and correct my Membership status to reflect my actual continuous 10+ years of service.
