Prior Years of Service not counted towards my Xfinity Rewards Tier

I had service from 2005 - 2013 while I was in a condo, then the service was transferred to our new home in 2013.  I just noticed today that there was a Diamond status for 14 plus years and thought why does mine only show platinum.

My service for the past 20 years has all been under my same name as well.

@sn0731 Most likely the old account is not linked to the current account, so it is not recognizing the full history. Have you tried linking them with the instructions I provided above?

That is from back in 2013, if there was another account number which I'm not sure whey there would have been as the service was just transferred,  I wouldn't even know what it was anymore.

@sn0731 Each address would have its own unique account number. We can check into them and worst case submit a request with our rewards team to link the history. Can you please send us a direct message with your full name and both the current and previous service addresses?
