This is happening to me also for the past two years.  In 2017 or 20188 we changed the business name when my father retired.  I was told to use the same username even though I was given a new account, have a new eFIN and tax ID.  Now that I am using eSignature, clients tell me that my father's company name is still listed.  DocuSign support says that it is connected to his email which no longer is active, and he NEVER used eSignature.  Docusign told me that I have to change it, Proseries says go make the change by logging into my account, but it isn't there.  Now I'm told that I need to change my username to my business name or my email address.  We tried that last year and while I don't remember why, I'm still using the old username. I can't expand my business within the virtual world if the business name is incorrect.
