Bereavement Request and Mobile Device Listed Twice

Father passed away, I am now Primary account holder. I require full account authority not just Primary. I am paying the bills. I've submitted the Death Certificate twice using the Bereavement Request Submission link nothing has been done yet. Also for unknown reasons his mobile account has the same phone showing up twice, 1 is showing the phone number that is active, however it states "SIM is now paired with a different device. All network-related features will apply to that device. All billing-related functions — such as device upgrades and monthly payments — are still paired with the original device." which makes sense because I see a 2nd IMEI number below on the same page, however it's the same exact phone, it is not different. This may be why I can't trade it in right now as it refuses. Also I tried adding the real IMEI number as a Bring Your Own Phone but all it did was add a useless duplicate of the same phone that's not activated. Any help appreciated.
