You have two options for changing a calling plan for an employee:  1) Do it yourself by deleting and recreating the user or 2) Submit a request to Aptela’s billing team. 

To Delete and Recreate the user, step-by-step instructions are found in the article:  How to Add a Standard User. 

To submit a request to Aptela’s billing team, fill out a form found here.
Be sure to clearly identify the user name(s) and calling plan(s) you are looking to change.
