Thanks for the speedy response. I don't have the ticket # handy. The email the account was associated with is firstname.lastname@example.org.
An employee set up a business account using the (my) business account credit card. That employee has moved on and their email address is no longer active. There is no way for me to log in to the account and deactivate it! I have requested that support cancel the account on a previous occasion, without resolution. Please offer me some direction on how to cancel the account!
