Changing name of service doesn't change internal address

I changed the name of my service, but the internal address doesn’t seem to have changed. How do I change this?

Also, I changed the name of a database, but I want to know how to change the database name and user name. I could not find any info on this. Thank you.

The internal address of a service and the database-name for a database remain constant for a given resource since these are unique identifiers that can’t be changed. You can try re-creating the resources with the new names, or email if creating new resources is not an option, so we can take a look.
