My service requests isn't working

[TCF]

I have done several service requests to change the user name on a phone number, it says its completed but on Bill analyser, the change hasn't been made.

I changed them last year in the same way with no issue, now it doesn't work.

It is saying the status is closed and completed but it has not changed anything.
