Changed EA ID - Only Changed in Some Places

Howdy,

Recently discovered my EA ID was wrong, somehow it had reverted to one I hadn't used since the 2000s. Can't change it back to the correct EA ID because it's in use (by me), so had to stick a 0 on the end - **bleep**!

Anyway I changed my EA ID through the website, and the website accepted it and displays the new ID in the top right corner. However it only changed in some places, Help, Forums and EA App all show the old ID. Example in the attachment, left is the account website, right is EA App.

Have had a couple of goes at fixing this through EA Help, but I keep getting fobbed off by chat support. They tell me they've elevated the ticket and someone will get back to me, and then my case is marked as either "Waiting for Player" or "No Fix". So far I've never actually heard from the higher tier technicians they promise to forward my issue too.

Given they "helpfully" suggested I might have more luck via the forums - has anyone else had this issue with their EA ID getting glitched?

PS: Couldn't see a forum for EA Account, so filed under the App
