Unable to view account info online after move

When I login with xfinity id, my old service address and new one are listed (two separate accounts linked), however I can only log into the old one which is disconnected. My current new address is listed as inactive and I can't switch to it, even though it is active and I've been paying my bill under the new account for months. I'd like this resolved as I cannot view billing or other info when logging in.
