Rewards

I have been in my current address since 2019 (it will be 5 years in June). Prior to that, I had Xfinity at another address. I did the move option when we moved to transfer my service in 2019 & someone came out to hook everything up when we made the move. I am only a Gold Rewards member but I am reading this is based on how long you have been a customer & that if you move your service to another address, it will not affect your status. So why am I only Gold when I have had Xfinity for at least 10 years, if not longer?
