Remove addresses associated with old account

When I try to manage my account, in any way, it shows my same address 3 times.   2 of them are inactive but it never tells you which ones and it is ridiculously cumbersome with the slow loading times of Xfinity website and app.   So for example if I click the top one it might hang for 30 seconds then say.  "We're sorry. Please contact us and one of our friendly and knowledgeable representatives can help."  I tried that and the person was completely baffled and said we don't have a team for that but I can help change your service.  I just want to be able to shop and manage my account on my own.

If I go to account details it only shows one address so it's not there.  Any assistance would be greatly appreciated.
