Hi @kevilleagency,
I'd be glad to lend you a hand in this query about the charge you mentioned.
So I can provide you the correct steps to resolve this, I'm going to have to ask for additional details. What is this specific charge you mentioned, and where is it visible when you send an invoice?
So you'll be familiar with the hours of operation for our Technical Support teams, take a look at this article: Support hours and types.
I'll be looking forward to hearing back from you. Post a comment below, and I'll be sure to get back to you.
